[" Three point charges "q,-2q" and "-2q" are placed at the vertices of an equilateral triangle orsice a."2140],[" done by external forces to increase their separation to "2a" ? "]

Three point charges IC, -2C and -2C are placed at the vertices of an equilateral triangle of side I m. The work done by an external force to increase the separation of the charges to 2 m in joule is ( epsilon_(0) = Permittivity of air)

Three point charges 1C, -2C and -2C are placed at the vertices of an equilateral triangle of side length one meter. The work done by an external force to increase the separation of the charges to 2 meters in joules is: ( in_(0) is permittivity of air)

The point charges -2q, -2q and +q are put on the vertices of an equilateral triangle of side a . Find the work done by some external force in increasing the separation to 2a (in joules).
