Problem 29 Easy Difficulty

Figure $\mathrm{P} 20.29$ shows a bar of mass $m=0.200 \mathrm{kg}$ that can slide without friction on a pair of rails separated by a distance $\ell=$ 1.20 $\mathrm{m}$ and located on an inclined plane that makes an angle $\theta=25.0^{\circ}$ with respect to the ground. The resistance of the resistor is $R=1.00 \Omega,$ and a uniform magnetic field of magnitude $B=0.500 \mathrm{T}$ is directed downward, perpendicular to the ground, over the entire region through which the bar moves. With what constant speed $v$ does the bar slide along the rails?

Answer

\mathrm{v}=2.8 \mathrm{m} / \mathrm{s}

{'transcript': "In the given problem, there is an inclined plane this which is inclined at an envelope 25 degree. There are two reels, or this incline, which are, and secondly, a long incline. One off, the really is visible to us, and the other rail is within the plane off paper, which is not visible to us. And over these reels, this ISS a metallic roar which is slighting downward under the influence off. It's sweet it's with is mg Acting don't work, so it's on one x will be mg pasta as if this Angeles Tater 25 degree This angle will also be 25 degree and this continent along the rails is mg sign Peter all trying to find any began sick So the raw is sliding over the rails under the influence of this, and design went effectively No, there is a magnetic will also, which is also particular number. So its components we'll also be like this. She would be given by B cause 25 degree. So when the order will be sliding down, it will be intercepting this be cost 25 degree so emotionally imagery being used. It grows the aims of the road. The distance between the two reels he's given us and is where 1.0 neater. The speed off the road downward that is missing. Letting TV which we have to find the resistance. The rails are joined me there Assistance Also some factors The stances giving us 1.0 Oh mass off the road is zero blind. It was 00 Can't you? And the magnet if you're be his Siegel wind 500 s you So the e m f IND used will be given by the emotional Imagine use will be a component of the magnet Will be cost 25 degree into the in tow. So the current induced in the road will become using Onslow something by our means. Me cost 25 degree B l my are This is Rita Couldn't in the roar. Do you know this current? Our force will act over the snore Was direction BB like this? This force will left over. There are so the single again will be 25 degree. So the component of the force opposing the motion off the road will be if course 25 degree, the force will be given as be in tow, I in tow l So it will become be into be cost 25 degree to be in tow. L f i r into l This will be the force which ultimately becomes the square We in tow elsewhere cost 25 degree my are so in order to have the constant velocity, the there should be no net for stepping on the road. So M designed 25 initial people who f course 20 practically so f cost 25 degree is where toe MGI signed 25 degree. Or we can say these sweat v Early square course 25 degree my, uh equals m g sign 25 degrees. So finally the expression for velocity becomes N g r Sign 25 degree divided by bees. Where early square Across the square, 25 degree My put the values was your point. Bouquet G for the mosque, 9.8 for acceleration to gravity G into resistance. One into sign 25 degree divided by the square means your 0.5 square into length of the roar. And because the square 25 degree the new editor come on comes out of the zero point it to it and the nominee turd 0.296 When I calculated I'll get to point eight meters per second. So the roar will come down with the speed off 2.8 meters per second. The constant velocity. Thank you."}
