Re: Circular Motion MHT CET MCQ

As you preparing for MHT CET exam and looking for MCQ questions on Circular Motion, here I will provide you.

Here are some questions

(a) a radial acceleration
(b) a tangential acceleration
(c) zero acceleration
(d) both tangential and radial accelerations

A body is traveling in a circle at constant speed. It
(a) has constant velocity.
(b) has no acceleration
(c) has an inward acceleration
(d) has an outward radial acceleration

A body of mass 100 gram, tied at the end of a string of length 3 m rotates in a vertical circle and is just able to complete the circle. If the tension in the string at its lowest point is 3.7 N, then its angular velocity will be ______ (g = 10 m/s2)
(a) 4 rad/s
(b) 3 rad/s
(c) 2 rad/s
(d) 1 rad/s

A body of mass 500 gram is rotating in a vertical circle of radius 1 m. What is the difference in its kinetic energies at the top and the bottom of the circle?
(a) 4.9 J
(b) 19.8 J
(c) 2.8 J
(d) 9.8 J

A bucket containing water is tied to one end of a rope of length 2.5 m and rotated about the other end in a vertical circle. What should be the minimum velocity of the bucket at the highest point, so that the water in the bucket will not spill? (g = 10 m/s2)
(a) 2.5 m/s
(b) 4 m/s
(c) 5 m/s
(d) 7 m/s

A bucket tied at the end of a 1.6 m long string is whirled in a vertical circle with a constant speed. What should be the minimum speed so that the water from the bucket does not spill when the bucket is at the highest position?
(a) 4 m/sec.
(b) 6.25 m/sec.
(c) 16 m/sec.
(d) None of these

A can filled with water is revolved in a vertical circle of radius 4 metre and the water does not fall down. The time period of revolution will be
(a) 1 sec
(b) 10 sec
(c) 8 sec
(d) 4 sec

A car is moving in a circular track of radius 10 metre with a constant speed of 10 m/sec. A plumb bob is suspended from the roof of the car by a light rigid rod of 1 metre long. The angle made by the rod with the track is
(a) zero
(b) 30°
(c) 45°
(d) 60°

A car is moving in horizontal circular track of radius 10 m, with a constant speed of 36 km/hour. A simple pendulum is suspended from the roof of the car. If the length of the simple pendulum is 1 m, what is the angle made by the string with the track?
(a) 30°
(b) 45°
(c) 60°
(d) 90°

A car is moving on a circular path and takes a turn. If R1 and R2 are the reactions on the inner and outer wheels respectively, then
(a) R1 = R2
(b) R1 < R2
(c) R1 > R2
(d) R1 ≥ R2

A car moving on a horizontal road may be thrown out of the road is taking a turn
(a) by the gravitational force
(b) due to the lack of proper centripetal force
(c) due to the lack of frictional force between the tire and the road
(d) due to the reaction of the ground
