Physics Question on Magnetic Force

Question

A single turn current loop in the shape of a right angle triangle with sides 5cm, 12cm, 13cm is carrying a current of 2A. The loop is in a uniform magnetic field of magnitude 0.75T 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 $\frac{x}{130} N$ . The value of x is ________

Accepted Answer

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

Force on 5cm side is
∣F∣= ILB sinθ
=(2)(5×10−2)×43×1312=1309N
So, x=9

Hence, The correct answer is 9.
