Hi friends, in the first question here it is given a straight wire of infinite length carrying the current of 5 .9 ampere.
00:16
There is a rectangular loop.
00:18
Sorry, there is a rectangular loop having the dimension as shown in the figure and carrying the current i2.
00:37
I2 is given 15 amp.
00:43
Value of c is 0 .1 meter.
00:50
Value of a is 0 .15 meter and is 0 .45 meter.
01:01
We have to find the force.
01:07
Force on the loop due to state conductor will be mu not i1 i2 into l upon 2 pi into c minus mu not i 1 i2 l upon 2 pi a plus c and the nature of forces attractive towards a straight wire.
01:34
Now simplifying it, mu not i1, i2l upon 2 pi would be constant.
01:43
1 upon c minus 1 upon a plus c.
01:47
Now substituting the value, you will get the answer.
01:51
Mu not is 4 pi 10 to the power minus 7.
01:55
I1 is 5 .9.
01:57
I2 is 15 length is given 0 .45 c is 0 .1 a is 0 .1 plus 0 .15 simplifying it force you will get 1 .59 10 to the power minus 3 neuter and this is attracted towards left second part electron is moving with the speed of 1 .5...
