Question

what force will an
electron experience in a uniform electric Field of 2×10^3 newton.​

Answer 1

• Intensity of electric field, E = 2 × 10³ N/C

• Let the force experienced be F.

The intensity of electric field is defined as the force experienced by the unit charge placed at that point.

E = F/q

Where q is the charge of electron, q = e = 1.6 × 10^-19 coulomb.

$E = \dfrac{F}{q} \\ \\ 2 \times {10}^{3} = \dfrac{F}{1.6 \times {10}^{ - 19} } \\ \\ F = 2 \times {10}^{3} \times 1.6 \times {10}^{ - 19} \\ \\ F = 3.2 \times {10}^{(3 - 19)} \\ \\ F = 3.2 \times {10}^{ - 16} \: newton$

The force experienced in uniform electric field is 3.2 × 10^-16 N.
