Three charges of magnitude 30x10 4 c each located at x10m...

Three charges of magnitude 3.0x10^-4 C each are located at x=1.0m, y=0.0m, at x=0.0m, y=0.0m, and at x=-1.0m, y=0.0m. The one in the middle is positive, while the other two are negative. What is the net coulombic force exerted by them on a negative 3.0x10^-5 C charge located at x=0.0m, y=2.0m?

Transcript

00:01 In this question, we will calculate the net coulombic force exerted by them on a negative that is 3 times 10 density power minus 5 coulum of charge located at 0 .0 meter and for y coordinate 2 meters.

00:15 Now, from the figure, from this figure, we can very clearly say that the value for f1.

00:25 Let's write over here.

00:26 F1 is equal to 9 times 10 density power 9 times 3 times.

00:34 10xity power minus 5 times 3 times 10 density power minus 4 over 1 minus 0 whole square plus 0 minus 2 whole square simplifying this will give us exactly 3 times 10 necessarily power minus 5 that is due to 3 times 10 xity power minus 4 quorum now f2 is equal to 9 times 10 to the power 9 times 3 times 10 to the power minus 5 times 3 times 10 to the power minus 4 over minus 1 minus 0 whole whole square plus 0 minus 2 whole square simplifying this will give us exactly minus 3 no this is not the value actually let's just keep these two these are the expressions for f1 and f2 let's just keep them like this for a while yeah and for f3 our expression will be this nine times tenor should be power nine times three times ten density power minus five times three times ten density power minus four over zero minus zero whole square plus zero minus two whole square now therefore f1 is equal to f2 that is equal to 9 times tendency the power 9 times 3 times 10 sd power minus 4 times 3 times 10 sd power minus 5 over 5 times 10 energy power minus 4 okay now this will be equal to 16 .2 times 10 density power 4 newton this is basically attractive course attraction now, f3 is equal to 9 times 10 x .7 .9 times 3 times 10 x .7 .5 over 4 times 10 energy the power minus 5.

03:48 Over 4 times 10 energy power minus 4.

03:53 Simplifying this will give us f3 is equal to 20 .25 times 10 density power 4.

04:06 This is repulsive...
