The total energy of a particle, executing simple harmonic motion isAns) In simple harmonic motion when a particle is displaced to a position from its mean position, then its kinetic energy gets converted into potential energy and vice-versa. Therefore, total energy of a particle remains constant or the total energy in simple harmonic motion does not depend on displacement x.
(a) You have studied that plane and convex mirrors produce virtual images of objects. Can they generate real image under some circumstances? Explain. (b) A virtual image we a
The radius of an atom is of the order of: (1) 10 -10 cm (2) 10 -13 cm (3) 10 -15 cm (4) 10 -8 cm Ans: (4)10 -8 cm
Magnification is the ratio of size of image to the size of object. hence it is a dimensionless constant. It has no units. 1/m is not its unit.(1/m is the unit of power=DIOPTRE)
