Question

a positive charge of 2.0c and a positive charge of 3.0c are separated by 80m. what is the magnitude of the forces between the two charges

Answer 1

Given data

*The given positive charge is q = 2.0 C

*The second positive charge is Q = 3.0 C

*The distance between the charges is r = 80 m

The formula for the magnitude of the force between the two charges is given as

`F=\frac{\text{kqQ}}{r^2}`

*Here k is the Coulomb's constant

Substitute the values in the above expression as

`\begin{gathered} F=((9*10^9)(2.0)(3.0))/((80)^2) \\ =8.4*10^6\text{ N} \end{gathered}`

Hence, the correct option is (a)
