A single turn current loop in the shape of a right angle triangle with sides 5 cm , 12 cm , 13 cm is carrying a current of 2 A . The loop is in a uniform magnetic field of magnitude 0 . 75 T whose direction is parallel to the current in the 13 cm side of the loop. The magnitude of the magnetic force on the 5 cm side will be x 130 N . The value of x is _______.

Correct answer

0

Step-by-step solution

Here, B = 0 . 75   T The magnitude of magnetic force on the 5   cm side is F A B = i × l A B B sin θ                       angle between   A C   &   A B = 2 × 5 100 × 0 . 75 × 12 13 = 9 130   N Hence, the value of x = 9 .
