A uniform square plate has a small piece Qof an irregular shape removed and glued to the centre of the plate leaving a hole behind. Then the moment of inertia about the z-axis

A quantity X is given by 0 where  is the permittivity of the free space, L is a length, ∆V is a potential difference and ∆t is a time interval. The dimensional formula for X is the same as that of

A particle starts its motion from rest under the action of a constant force. If the distance covered in first 10 seconds is S₁ and that covered in the first 20 seconds is S₂ then:

A vector of magnitude b is rotated through angle θ. What is the change in magnitude of the vector?

A ball of mass 10 g moving perpendicular to the plane of the wall strikes it and rebounds in the same line with the same velocity. If the impulse experienced by the wall is the velocity of the ball is

A 2 kg block slides on a horizontal floor with a speed of 4m/s. It strikes a uncompressed spring, and compresses it till the block is motionless. The kinetic friction force is 15N and spring constant is 10000 N/m. The spring compresses by
