A current carrying closed loop in the form of a right angle isosceles triangle A B C is placed in a uniform magnetic field acting along A B . If the magnetic force on the arm B C is F , the force on the arm A C is

Options

  1. A- F
  2. BF
  3. C2 F
  4. D- 2 F

Correct answer

A. - F

Step-by-step solution

gathered F _ A B =0 F _ A B + F _ B C + F _ C A =0 F _ B C + F _ C A =0 F _ C A =- F _ B C =- F gathered
