Select the correct answer.

What is the electric field experienced by a charged balloon if the charge on the balloon is [tex]$9.4 \times 10^{-10}$[/tex] coulombs and the force it experiences is [tex]$8.2 \times 10^{-2}$[/tex] newtons?

A. [tex]8.7 \times 10^7[/tex] newtons/coulomb

B. [tex]94 \times 10^{11}[/tex] newtons/coulomb

C. [tex]94 \times 10^7[/tex] newtons/coulomb

D. [tex]8.7 \times 10^{-9}[/tex] newtons/coulomb



Answer :

To find the electric field experienced by the charged balloon, we can use the formula for the electric field [tex]\( E \)[/tex], which is given by:

[tex]\[ E = \frac{F}{q} \][/tex]

where:
- [tex]\( F \)[/tex] is the force experienced by the charged object,
- [tex]\( q \)[/tex] is the charge on the object.

From the question, we have:
- The charge on the balloon, [tex]\( q = 9.4 \times 10^{-10} \)[/tex] coulombs,
- The force experienced by the balloon, [tex]\( F = 8.2 \times 10^{-2} \)[/tex] newtons.

Substituting these values into the formula, we have:

[tex]\[ E = \frac{8.2 \times 10^{-2}}{9.4 \times 10^{-10}} \][/tex]

When we perform this division, we get:

[tex]\[ E \approx 87234042.55319147 \][/tex] newtons per coulomb (N/C).

This is approximately equal to:

[tex]\[ E \approx 8.7 \times 10^7 \][/tex] N/C.

Therefore, the correct answer is:

A. [tex]\( 8.7 \times 10^7 \)[/tex] newtons per coulomb.
