Explanation:
The fundamental charge of a single electron is .
If there are 10 excess electrons, the net charge that would be measured should be 10 times the fundamental charge of a single electron:
Answer:
No the given statement is not necessarily true.
Explanation:
We know that the kinetic energy of a particle of mass 'm' moving with velocity 'v' is given by
Similarly the momentum is given by
For 2 particles with masses and moving with velocities
respectively the respective kinetic energies is given by
Similarly For 2 particles with masses and moving with velocities
respectively the respective momenta are given by
Now since it is given that the two kinetic energies are equal thus we have
Thus we infer that the moumenta are not equal since the ratio on right of 'i' is not 1 , and can be 1 only if the velocities of the 2 particles are equal which becomes a special case and not a general case.
