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

more than, less

less than, more

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
