Two large plates are given the charges as shown in figure. Now, the left plane is earthed. Find the amount of charge that will flow from the earth to the plate.

A

`14muC`

B

`-14muC`

C

`7muC`

D

`-7muC`

Text Solution

Verified by Experts

The correct Answer is:
B

Final charges will be as shown in fig. so charge flowing from earth to plate `=` final charge `-` intial charge `=-4-10=-14muC`
