Question

The charge q4 is now replaced by charge q5 which has the same magnitude, but opposite sign from q4 (i.e., q5 = -0.3 μC). What is the new value for the potential energy of the system?

Answer 1

the law of electric potential energy is\[V=\frac{ 1 }{ 4 \pi \epsilon _{0} }\frac{ q }{ r }\]

Answer 2

potential energy of positive charge will b positive

Answer 3

and potential energy of negative charge will b negative
