Question

What is the force acting on an electron in an electric field of strength 2400Vm^-1?

Answer 1

Use the following formula for the electric force:

`F=qE`

where,

q: charge of the electron = 1.9*10^-19C

E: Electric field magnitude = 2400Vm^-1

Replace the previous values of the parameters into the formula for F and simplify:

`F=(1.6\cdot10^(-19)C)(2400(V)/(m))=3.84\cdot10^(-16)N`

Hence, the force acting on the electron is 3.84*10^-16 N
