A Particle of unit mass undergoes one-dimensionalmotion such that its velocity varies according tov(x) = βx2nwhere b and n are constants and x is the positionof the particle. The acceleraion of the particle asa function of x, is given by :
When two dispalcements represented byy1 = asin(ωt) and y2 = b cos(ωt) are superimposedthe motion is :
One mole of an ideal diatomic gas undergoes atransition from A to B along a path AB as shownin the figure,
The change in internal energy of the gas during the transition is :
An electron moving in a circular orbit of radius rmakes n rotations per second. The magnetic fieldproduced at the centre has magnitude :
The interference pattern is obtained with two coherent light sources of intensity ratio n. In the interference pattern, the ratio Imax-Imin/Imax+Imin will be
An air bubble in a glass slab with refractive index 1.5 (near normal incidence) is 5 cm deep when viewed from one surface and 3 cm deep when viewed from the opposite face. The thickness (in cm) of the slab is
