Eight equal point charges each of charge 'q' and mass 'm' are placed at eight corners of a cube of side 'a'

If keeping all other charges fix, charge of corner 'A' is released then find out its speed when it is at infinite distance ?

Text Solution

Verified by Experts

The correct Answer is:
`sqrt((2Kq^(2))/(ma)[3+3/(sqrt(2))+1/(sqrt(3))])`
