The force exerted by an electric field on a charge of +10 µC at a point is 16 × 10^-4 N. What is the intensity of the electric field at the point?
Given: q = 10 µC = 10 × 10-6 C, F = 16 × 10-4 N To find: Electric field intensity (E) Formula: E = \(\frac{F}{q}\) Calculation: From formula, E = \(\frac{16\times10^{-4}}{10\times10^{-6}}\) = 160 N/C
