The position vector of a particle in a circular motion about the origin sweeps out equal area in equal time
(b) speed remains constant (d) tangential acceleration remains constant. Explanation: Velocity and acceleration will not be constant because direction changes continuously. Hence option (a) and (c) are not correct. With a constant speed the position vector will...

A student says that he had applied a force F = k√x on a particle and the particle moved in simple harmonic motion.
(a) As x increases k increases. Explanation: Since the motion is simple harmonic, the force F=-⍵²x where ⍵² is a constant. Equating the force applied by the student we get, -k/x=-⍵²x →k=⍵²x² It is...

In an imaginary atmosphere, the air exerts a small force F on any particle in the direction of the particle's motion.
(b) The original point then t1 > t2. Explanation: Since F is in the direction of particle's motion it will add an acceleration in the direction of motion. Let it be a. Now magnitude...

"an object in rotational motion need not have periodic motion''. do you agree?discuss with an example
No. Generally rotational motion is a periodic motion. Periodic motion is a motion that repeats itself at regular time intervals. Rotational motion is a type of periodic motion. For example, the...
