Calculate the velocity (in m/s) of a 0.352-g object that hasEk= 22.8 J. m/s
Determine which of the following pairs of charged particles has the greater electrostatic energy between them: charges of +1 and -2 separated by a distance ofdor charges of +2 and -2 separated by a distance of 2d. Select the single best answer.
- charges of +1 and -2 separated by a distance of d have greater energy
- charges of +2 and -2 separated by a distance of 2d have greater energy
- both pairs have equal energy
