Imagine a third particle, which we will call a cyberon. It has three times the mass of an electron (3m). It has a positive charge that is three times the magnitude (3qe) of the charge on an electron. What is the ratio of the speed vc that the cyberon would have when it reaches the upper plate after being released from rest at position h0 to the speed ve that the electron would have
