Question

A conducting rod is extended from east to west direction in Earth magnetic field. If horizontal component of earth magnetic field is 0.3T find the direction and magnitude of induced emf in rod. If rod is falling with 90cm/ms speed.length of rod is 200
​

Answer 1

Explanation:

"One end of a steel rod of radius R = 10mm and length L = 80 cm is held in a vise. A force of magnitude F = 70000 N is then applied perpendicularly to the end face (uniformly across the area) at the other end, pulling directly away from the vise. What will be the elongation of the rod (in the unit meters)? Young modulus is 200 × 109 N/m2)
