If the potential energy at a displacement \(x\) is numerically equal to the square root of potential energy at a displacement \(y\), then (where \(\omega\) is angular velocity):

A liquid is flowing through a tube of diameter 9 mm with a speed of \(10\,cm\,s^{-1}\). If this tube is connected to a narrow tube in which the liquid flows with a speed of \(90\,cm\,s^{-1}\), then the diameter of the narrow tube is:

Surface tension of liquids is:

A horizontal metal rod of diameter 4 cm projects 6 cm from a wall. The shear modulus of the metal is \(3 \times 10^{10}\, N\,m^{-2}\). An object of mass 1100 kg is suspended from the free end of the rod. The free end of the rod moves down by a distance. (Take \(g = 10\,m\,s^{-2}\), neglect mass of rod)

An object is thrown directly away from Earth's surface. Its initial speed is \(V_0\) and escape velocity is \(V_E\). If the object reaches a distance of \(\frac{4R}{3}\) from the centre of the Earth, then the ratio \(\frac{V_E}{V_0}\) is:

A block of mass 50 kg is pushed on a frictionless inclined plane by a horizontal force F. The incline makes an angle of \(60^\circ\) with the horizontal. If the block moves with constant speed, then F is: (Take \(g=10\, m\,s^{-2}\))

A circular disc of weight 500 N and radius 1 m is started from rest by a constant horizontal force of 25 N applied tangentially to the disc. The kinetic energy of the disc after \(t = 2\,s\) is:

A person of mass 80 kg sits on a spring and compresses it by 2 m. If the person is projected at 20 m/s velocity by the spring, then the spring constant is (Take no energy loss):

A uniform force of \((4i + 3j) N acts on a body. The body is displaced from (4i - 3j - 2k)\,m to (5i - 4j + 2k)\,m. Then the work done by the force on the body is in joule:

A rod of mass M and length 2L lies horizontally. A particle of mass m, moving with velocity v in the vertical plane, strikes the end B of the rod and sticks to it. Then the velocity of point B just after collision is:

Three bodies A, B and C of masses 10 g each are tied to a thread–pulley system as shown in the figure. Assume the masses of pulley and threads are negligible and there is no friction in the pulley. The coefficient of friction between A and B with the horizontal surface is 0.1. Find the acceleration with which body C comes down. (Take \(g = 10\, m\,s^{-2}\))
