Charges Q1 and Q2 lie inside and outside...

Charges `Q_1` and `Q_2` lie inside and outside respectively of a closed surface S. Let E be the field at any point S and `phi` be the flux of E over S.

A

If `Q_1` changes, both E and `phi` will change.

B

If `Q_2` changes, E will changes but `phi` will not change.

C

If `Q_1 = 0 and Q_2 !=0`, then `E!= 0 but phi = 0`

D

If `Q_1 = 0 and Q_2 !=0`, then `E= 0 but phi != 0`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`E` depends upon both `Q_(1)` and `Q_(2)` . But `phi` depends only on `Q_(1)`.
