A particle of mass m is observed from an inertial frame of reference and is found to move in a circle of

(d) both A and B are false. Explanation:  With the application of pseudo force in a noninertial frame of reference velocities change, so do linear momentum and kinetic energy because both depend...

(c) 0 Explanation:  Since the body is uniformly rotating, the resultant force on the particle P will be in the radial direction. So again the directions of A and B will be...

(c) horizontal and intersecting the axis Explanation:  Since the body is rotating uniformly, a particle not on the axis moves in a uniform circular motion. This circle will be horizontal with its center at...

(a) along the velocity of the wheel Explanation:  Perimeter of the wheel = 2π*0.20 =0.4π =1.26 m  But it moves only 0.60 m.  So the wheel slips on the road. At the point of...

(b) cannot be an inertial frame because the earth is revolving around the sun (d) cannot be an inertial frame because the earth is rotating about its axis. Explanation: A reference frame attached...

(c) the frame may be inertial but the resultant force on the particle is zero (d) the frame may be noninertial but there is a nonzero resultant force. Explanation:  (a) is incorrect because...

(a) Both the frames are inertial. (b) Both the frames are noninertial. Explanation: S1 is moving with constant velocity w.r.t frame S2 . So, if S1 is inertial, then S2 will be inertial...

The correct answer is (d) F1 = 0, F2 = 0. Explanation: (a), (b) and (c) are possible under different values of accelerations of the frames S1 and S2 with respect to another inertial...

(d) zero. Explanation: Centrifugal force is a pseudo force needed in an non-inertial frame of reference when we still want to use the Newton's Laws. In this case the frame of reference is...

(c) horizontal and intersecting the axis Explanation:  Since the body is rotating uniformly, a particle not on the axis moves in a uniform circular motion. This circle will be horizontal with its...
