A 1.0 meter long rod is held horizontally in the east-west direction on a distant planet and is dropped from a height of 1.23 m. The horizontal component of the planet's magnetic field is 6.93e-05 T. Find the emf induced between the ends of the rod just before it hits the ground.

The induced emf between two end is V

Explanation:

Given:

Length of rod m

Height m

Magnetic field T

For finding induced emf,

Where velocity of rod,

For finding the velocity of rod.

From kinematics equation,

Where initial velocity,

Put the velocity in above equation,

    V

Therefore, the induced emf between two end is V
