A spring of force constant 200Nm^(-1) has a block of mass 10 kg hanging at its one end and the other end of the spring is attached to the celling of an elevator. The elevator is rising upwards with an acceleration of g/4 and the block is in equilibrium with respect to the elevator . when the acceleration of the elevator suddenly ceases , the block starts oscillating . What is the amplitude (in m) of these oscillations ?

Starting from rest a wheel rotates with uniform angular acceleration 2pirads^(-2) . After 4s, if the angular acceleration ceases to act, its angular displacement in the next 4s is

Calculate the total K.E. of earth, assuming it to be a uniform spherical body moving around the sun with a speed of 30 km s^(-1) and spinning about its own axis? Mass of earth = 6 xx 10^(24) kg, Radius of earth = 6400 km ?

A circular coil has moment of inertia "0.8 kg m"^(2) around any diameter and is carrying current to produce a magnetic moment of 20Am^(2) . The coil is kept initially in a vertical position and it can rotate freely around a horizontal diameter. When a uniform magnetic field of 4 T is applied along the vertical, it starts rotating around its horizontal diameter. The angular speed the coil acquires after rotating by 60^(@) will be :

Orbital velocity of a satellite in its orbit (around earth) of radius r is v. It collides with another body in its orbit and comes to rest just after the collision. Taking the radius of earth as R, the speed with which it will fall on the surface of earth will be :

Assertion : In the s-t diagram as shown in figure, the body starts moving in positive direction but not form s = 0. Reason : At t = t_(0) , velocity of body changes its direction of motion.

In the following figure, a body of mass m is tied at one end of a light string and this string is wrapped around the solid cylinder of mass M and radius R. At the moment t = 0 the system starts moving. If the friction is negligible, angular velocity at time t would be

A long horizontal plank of mass m is lying on a smooth horizontal surface. A sphere of same mass m and radius r is spinned about its own axis with angular velocity we and gently placed on the plank. The coefficient of friction between the plank and the sphere is mu . After some time the pure rolling of the sphere on the plank will start. Answer the following questions. Find the time t at which the pure roiling starts

An electron in an atom can be completely designated with the help of four quantum numbers. Out of these, the first three i.e., principal (n), azimuthal (l) and magnetic (m) quantum number are obtained from the solution of Schrödinger wave equation while the spin(s) quantum number arises from the spin of the electron around its axis clockwise or anticlockwise. Of these principal quantum number tells about the size, azimuthal quantum number about the shape and magnetic quantum signifies the orientation of the electron orbital. The electronic configuration of P in H_(3)PO_(4) is
