Question

3) 3 A force of -4.4x10^33 N exists between a positive charge of 8.0x10^-4 C and a

negative charge -3.0x10^-4 C. What is the distance that separates the charges?

Answer 1

`r=7* 10^(-16)\ m`

Step-by-step explanation:

The force between charges,
`F=-4.4* 10^(33)\ N`

Positive charge,
`q_1=8* 10^(-4)\ C`

Negative charge,
`q_2=-3* 10^(-4)\ C`

We need to find the distance between charges. The force of attraction between charges is given by :

`F=(kq_1q_2)/(r^2)`

Where

r is the distance between charges

`r=\sqrt{(kq_1q_2)/(F)} \\\\r=\sqrt{(9* 10^9* 8* 10^(-4)* 3* 10^(-4))/(4.4* 10^(33))} \\\\r=7* 10^(-16)\ m`

So, the distance between charges is
`7* 10^(-16)\ m`.
