A particle is observed from two frames S1 and S2 . The frame S2 moves with respect to S1 with an acceleration a. Let F1 and F2 be the pseudo forces on the particle when seen from S1 and S2 respectively. Which of the following are not possible ?
(a) F1 = 0, F2 ≠ 0 

(b F1 ≠ 0, F2 = 0

(c) F1 ≠ 0, F2 ≠ 0 

(d) F1 = 0, F2 = 0.

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 frame. But (d) is not possible because due to difference in accelerations of frames the pseudo forces in both frames cannot be equal.

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

(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 inertial, so there is no centrifugal...

A particle moves with a constant velocity parallel to the X-axis. Its angular momentum with respect to the origin.

(b) remains constant Explanation:  Since the particle moves with a constant velocity along a straight line, the distance of the line from the origin (r) remains constant. The linear momentum of the...

The acceleration of moon with respect to earth is 0.0027 m/s^2 and the acceleration of an apple falling on earth's

(b) 0.0027 m/s2    Explanation:  When moving in the orbit, the moon balances the force on it by the earth with its uniform circular motion in the orbit resulting in centrifugal force. When...

A particle stays at rest as seen in a frame. We can conclude that (a) the frame is inertial

(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 particle is found to be at rest when seen from a frame S1 and moving with a constant velocity when seen from another frame S2.

(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...

Consider the following two equations (A) L = Iω (B) dL/dt = T In noninertial frames (a) both A and B are true

(b) A is true but B is false Explanation:  dL/dt = total torque of external force, not equal to any torque.  So dL/dt = Γ is not correct.

Assertion (A) : In a motion picture, usually 24 frames are projected every second over the whole length of the film.

(c) A is correct but an image formed on the retina of eye persists for about 1/16 sec(0.06 sec) after it changes.
