In this question, we have to find the range of function from k to K. Here we know that sin^-1x + cos^-1x = and it only defines if -1 ≤ x ≤ 1 . And tan^-1x lines in () to ( ) .

In an experiment with a beam balance an unknown mass m is balanced by two known masses of 16 kg and 4 kg as shown in figure. The value of the unknown mass m is :–

A particle starts from the point (0m, 8m) and moves with uniform velocity of m/s After 5 seconds, the angular velocity of the particle about the origin will be

A particle of mass M is at a distance a from surface of a thin spherical shell of equal mass and having radius a

There is a concentric hole of radius R in a solid sphere of radius 2R. Mass of the remaining portion is M. What is the gravitational potential at centre ?

A thin rod of mass M and length L is struck at one end by a ball of clay of mass m, moving with speed v as shown in figure. The ball sticks to the rod. After the collision, the angular momentum of the clay-rod system about A, the midpoint of the rod, is

A non uniform rod OA of liner mass density (= const.) is suspended from ceiling with hinge joint O & light string as shown in figure. Find the angular acceleration of rod just after the string is cut
