Okay, so to find the magnitude of the force, we are going to use the formula.
00:06
F equal to i times b times l, sine theta, where i is the current, p is the magnetic field, and l is the length of the while.
00:17
So let us first find the force on the first segment, ab.
00:23
So we have f equal to 1 time 0 .3 times 50 times 10 to the negative 2 .000.
00:36
And sign of 0 because the angle for the segment ab is 0.
00:43
On solving this we have f equal to 0.
00:46
There is the magnitude of force on the segment ab is 0.
00:51
Now we'll find the force on the segment bc.
00:55
So we have f equal to 1 times 0 .3 times 8 times 10 to the negative 2 and multiplied by sign of 90 degree.
01:15
So on solving this we have force equal to 0 .04 newton...
