What is the electric field experienced by a charged balloon if the charge on the balloon is 9.4 * 10^-10 coulombs and the force it experiences is 8.2 * 10^-2 newtons?

A. 8.7 * 107 newtons/coulomb

B. 9.4 * 10-11 newtons/coulomb

C. 9.4 * 107 newtons/coulomb

D. 8.7 * 10-9 newtons/coulomb

Answer : A

Given data

Charge on the balloon (q) = 9.4 * 10⁻¹⁰ coulombs,

Force experiences (F) = 8.2 * 10⁻² N,

determine the electric field experienced by charged balloon (E) = ?

We know that,

F = q. E Newtons

=> E = F/q Newtons/Coulomb

=> E = (8.2 * 10⁻² N) / (9.4 * 10⁻¹⁰ C)

= 8.72 * 10⁷ Newtons/Coulombs

E = 8.72 * 10⁷ N/C

Electric field experienced by the charged balloon is 8.72 * 10⁷ N/C
