Question

Calculate the force on an electron in a uniform electric field of 3*10^14NC^-1 due north

Answer 1

Given:

• Electric field $= 3 \times 10^{14}NC^{-1}$

To Find:

• Calculate the force on an electron.

Solution:

        Charge on electron $(q_E)$ $= 1.6 \times 10^{-19} C$

Force on an electron

           $F = E \times q_E$

          $F = 3 \times 10^{14} NC^{-1} \times (-1.6 \times 10^{-19} C)$

          $F = -8 \times 10 ^{-15}N$

Thus, force on an electron $F = -8 \times 10 ^{-15}N$
