A satellite orbits the Earth at a height equal to the Earth's radius R from the surface. The orbital velocity of the satellite is: (Take g as acceleration due to gravity at Earth's surface)

A particle of mass 2 kg moves along a straight line with velocity v = (3t² − 4t + 1) m/s. The net force acting on the particle at t = 2 s is:

A semiconductor diode is used in a circuit to convert alternating current (AC) into direct current (DC). This process is called:

A photon of wavelength 3000 Å strikes a metal surface. The energy of the photon in eV is (h = 6.63 × 10⁻³⁴ J·s, c = 3 × 10⁸ m/s, 1 eV = 1.6 × 10⁻¹⁹ J):

A block of mass m is placed on a smooth inclined wedge of inclination theta and mass M. The wedge rests on a horizontal frictionless surface. The block is released from rest. The acceleration of the wedge relative to the ground, immediately after release, is:

A charged particle moves with velocity v in a uniform magnetic field B perpendicular to its direction of motion. The particle will move in:

A spherical ball of radius 3 mm and density 8000 kg/m³ falls through a viscous fluid of density 1000 kg/m³ and viscosity 1.0 Pa·s. The terminal velocity of the ball is (g = 10 m/s²):

A capillary tube of radius 0.05 mm is dipped in water. If the surface tension of water is 0.07 N/m, the angle of contact is 0, the height to which water rises in the capillary tube is: (density of water = 1000 kg/m, g = 10 m/s)
