As shown in the figure, a magnetic is moved with a a fast speed towards a coil at rest. Due to this, induced electromotive force, induced charge in the coil are `E`, `I` and `Q` respectively. If the speed of magnetic is doubled, the incorrect statement is

A

`E` increases

B

`I` increase

C

`Q` remains same

D

`Q` increases

Text Solution

Verified by Experts

The correct Answer is:
