Correct Answer

D

Explanation

To calculate the force acting on an electron in an electric field, we can use the formula:

Force (F) = charge (q) × electric field intensity (E)

Given:
Charge of the electron (q) = 1.6 × 10^-19 C (Coulombs)
Electric field intensity (E) = 10^-11 V/m (Volts per meter)

Substituting the values into the formula, we get:

F = (1.6 × 10^-19 C) × (10^-11 V/m)

Calculating this expression, we find:

F = 1.6 × 10^-19 × 10^-11 C × V/m
  = 1.6 × 10^-30 N

Therefore, the force acting on the electron is 1.6 × 10^-30 Newtons.
