In uniform electric field `E=10 N//C`, find

a. `V_A-V_B` , b. `VB-V_C`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
`a. V_BgtV_A,` So, `V_A-V_B` will be negative.
Further `d_(AB)=2cos60^@=1m`
`:. V_A-V_B=-Ed_(AB)=(-10)(1)=-10`volt
b. `V_BgtV_C, so V_B-V_C` will be positive
`Further, `d_(BC)=2.0m`
`:. V_B-V_C=(10)(2)=20`volt
