A shell travelling with a horizontal velocity of 100 m/sec explodes and splits into two parts, one of mass 10 kg and the other of 15 kg. The 15 kg mass drops vertically downward with initial velocity of 100 m/sec and the 10 kg mass begins to travel at an angle to the horizontal of tan”1 x, where x is

A body of weight ‘w’ placed on an inclined plane is acted upon by a force ‘P’ parallel to the plane which causes the body just to move up the plane. If the angle of inclination of the plane is ‘θ’ and angle of friction is ‘φ’, the minimum value of ‘P’, is

w sin (φ - θ)/cos φ

w sin (θ - φ)/cos φ

w cos (θ + φ)/cos φ

w sinθ cos(θ - φ)/sin φ

w sin (φ - θ)/cos φ

w sin (θ - φ)/cos φ

w cos (θ + φ)/cos φ

w sinθ cos(θ - φ)/sin φ
