Chapter 7 – Circular Motion

A car is moving with a speed of 30m/s on a circular path on a radius 500 m. It is increases its speed at the rate of 2m/sec^2 the resultant acceleration will be A car is moving with a speed of 30m/s on a circular path on a radius 500 m. It is increases its [...]

A car is travelling with linear velocity v on a circular road of radius r. If it is increasing its speed at the rate of a m/s^2 , then the resultant acceleration will be A car is travelling with linear velocity v on a circular road of radius r. If it is increasing its speed [...]

A particle moves on a circular path of radius 0.2 m with an angular acceleration 0.25 rad/s. The particle starts from rest, find the time at which the magnitude of radial acceleration and the magnitude of tangential acceleration are same. A particle moves on a circular path of radius 0.2 m with an angular acceleration [...]

A car passes along a curved path of a road according to the given figure moving with a speed of 72 km/hr, the radius of the curve is 10 m. If the mass of the car is 500 kg, reaction force on the car at lowest point of curved part will be : A car [...]

A racing completes three rounds on a circular racing track in one minute . If the car has a uniform centripetal acceleration of π^2m/s then radius of the track will be A racing completes three rounds on a circular racing track in one minute . If the car has a uniform centripetal acceleration of π^2m/s [...]

A particle is moving on circular path. The angle turned by radius vector is (1-e-^t/3). where θ is in radian and t is in second. The angular acceleration at t=0 is A particle is moving on circular path. The angle turned by radius vector is (1-e-^t/3). where θ is in radian and t is in [...]

A ball of mass 0.3kg is tied to one end of a string 0.8m long and rotated in a vertical circle. If the tension in the string be zero at the highest point of the circle, the tension at the lowest point in this situation will be equal to A ball of mass 0.3kg is [...]

A can filled with water is revolved in a vertical circle of radius 4 metre and the water just does not fall down. The time period of revolution will be: A can filled with water is revolved in a vertical circle of radius 4 metre and the water just does not fall down. The time [...]

One end of a string of length 1.0 m is tied to a body of mass 0.5 kg. It is whirled in a vertical circle with angular frequency 4 rad/s. The tension in the string when the body is at the lower-most point of its motion will be equal to (Take g = 10 m/s^2) [...]

A string 0.5 m long is used to whirl a 1 kg stone in a vertical circle at a uniform velocity of 5 m/s. What is the tension in the string when the stone is at the top of the circle? A string 0.5 m long is used to whirl a 1 kg stone in [...]
