Question

What is the electrical force of two punctiform electrical charges of 3ųC and 4ųC respectively at a distance of 10 cm in a vacuum

Answer 1

Electrical force, F = 10.8 N

Step-by-step explanation:

We have,

Charge 1,
`q_1=3\ \mu C=3* 10^(-6)\ C`

Charge 2,
`q_2=4\ \mu C=4* 10^(-6)\ C`

Distance between charges is 10 cm or 0.1 m

It is required find the electric force between two charges. The formula used to find the electrical force is given by :

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

k is electrostatic constant

Plugging all the values we get :

`F=(9* 10^(9)* 3* 10^(-6)* 4* 10^(-6))/((0.1)^2)\\\\F=10.8\ N`

So, the electrical force between charges is 10.8 N.
