Sr.# Question Answer
1 A body of mass 2 kg is thrown up vertically with K.E. of 490 joules. If the acceleration due to gravity is 9.8 m/s2, the height at which the K.E, of the body becomes half its original value is given by:
A. 50 m
B. 12.5 m
C. 25 m
D. 10 m
2 Choose the correct statement
A. Both an ammeter and voltmeter should have small resistance
B. Both an ammeter and a voltmeter should have large resistance
C. An ammeter should have large resistance and a voltmeter should have small resistance
D. An ammeter should have small resistance and a voltmeter should have large resistance
3 The essential distinction between X-rays andγ-rays is that
A. γ-rays have smaller wavelength than X-rays
B. γ-rays emanate from nucleus while X-rays emanate from outer part of the atom
C. γ-rays have greater ionizing power than X-rays
D. γ-rays are more penetrating than X-rays
4 The frequency of the incident light falling on a photosensitive metal plate is doubled, the kinetic energy of the emitted photoelectrons is
A. Double the earlier value
