Inside the box, a particle is projected with some velocity v with respect to the box at an angle θ as shown in the figure. Assertion (A) : The path of the particle with respect to an oberver sitting in the box will be a straight line. Reasoning (R ) : The acceleration of particle with respect to the box is zero. Then,

A box is falling freely. Inside the box, a particle is projected with some velocity v with respect to the box at an angle θ as shown in the figure. Assertion (A) : The path of the particle with respect to an oberver sitting in the box will be a straight line. Reasoning (R ) : The acceleration of particle with respect to the box is zero. Then,

A box is falling freely. Inside the box the time of flight is found to be t. The acceleration with which the lift is moving up is When a body is thrown up in a lift with a velocity u relative to the lift
