Question

When negative charges are kept in electric field then negative charges are accelerated by electric fields toward points:

• A. at lower electric potential
• B. at higher electric potential
• C. where the electric field is zero
• D. where the electric field is weaker
• E. where the electric field is stronger

Answer 1

Answer: (B)

at higher electric potential

We know that , $F=-\Delta U$, change in potential energy.

As charge is negative so, $F=-qE=-\Delta U$ or $\Delta U=qE$

So we will get change in potential as positive and hence the electric field should be towards points at higher potential.
