Select	Question
	In the Millikan's experiment, the distance between two horizontal plates is 2.5 cm and the potential difference applied is 250 V. The electric field between the plates will be
	The cathode rays have particle nature because of the fact that
	In Millikan's experiment for the determination of the charge on the electron, the reason for using the oil is
	The mass of a particle is 400 times than that of an electron and the charge is double. The particle is accelerated by 5 V. Initially the particle remained in rest, then its final kinetic energy will be
	An electron (charge =$1.6 imes {10^{ - 19}}C$) is accelerated through a potential of 100,000 V. The energy acquired by the electron is
	While doing his experiment, Millikan one day observed the following charges on a single drop (i) $6.563 \times {10^{ - 19}}C$ (ii) $8.204 \times {10^{ - 19}}C$ (iii) $11.50 \times {10^{ - 19}}C$ (iv) $13.13 \times {10^{ - 19}}C$ (v) $16.48 \times {10^{ - 19}}C$ (vi) $18.09 \times {10^{ - 19}}C$ From this data the value of the elementary charge (e) was found to be
	When electron beam passes through an electric field, they gain kinetic energy. If the same beam passes through magnetic field, then
	Which of the following law is used in the Millikan's method for the determination of charge
	The mass of the electron varies with
	When the speed of electrons increases, then the value of its specific charge
