Question

An L-shaped thin metal rod is moving with velocity 2i+4j in transverse uniform magnetic field of -4kt The potential difference between point A and B (VA – VB) will be

Answer 1

Answer:

56V

Explanation:

ε=(vxB) .I

εAC = 2 × 4 × 3

= 24 V

εCB = 4 × 2 × 4

= 32 V

εAB + εAC + εCB = 56 V
