1.	In a parallel-plate capacitor, the potential difference between the plates is V. A particle of mass m and charge -Q leaves the negative plate and reaches the positive plate with a momentum p. p is proportional to (a) m1/2 (b) Q1/2 (c) V1/2 (d) V
Answer» Correct Answer is: (a) m^1/2 ,(b) Q^1/2 ,(c) V^1/2 Energy = QV = p²/2m or p = (2mQV)^1/2.

Answer»

Correct Answer is: (a) m^1/2 ,(b) Q^1/2 ,(c) V^1/2

Energy = QV = p²/2m

or p = (2mQV)^1/2.
