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
