(B) The kinetic energy $K$ gained by a charged particle accelerated through a potential difference $V$ is given by the formula $K = qV$.Here,the charge of the particle is $q = 2e$,where $e$ is the elementary charge of an electron.The potential difference is $V = 5 \ V$.Substituting these values into the formula:$K = (2e) \times (5 \ V) = 10 \ eV$.Since the particle was initially at rest,its final kinetic energy is equal to the work done on it by the electric field,which is $10 \ eV$.
