Motion in a Pla...

A body of mass m moves in a circular path with uniform angular velocity. The motion of the body has constant

Three identical particles are joined together by a thread as shown in figure. All the three particles are moving in a horizontal plane. If the velocity of the outermost particle is v₀, then the ratio of tensions in the three sections of the strings is

A tachometer is a device to measure

A mass is supported on a frictionless horizontal surface. It is attached to a string and rotates about a fixed centre at an angular velocity ω₀. If the length of the string and angular velocity are doubles, the tension in the string which was initially T₀ is now

An aircraft executes a horizontal loop with a speed of 150 m/s with its wings banked at an angle of 12^o. The radius of the loop is (g = 10 m/s², tan12^o = 0.2126)

A particle is moving in a horizontal circle with constant speed. It has constant

A motor cyclist mocing with a velocity of 72 km/hr on a flat raod takes a turn on the road at a point where the radius of curvature of the road is 20 m. The acceleration due to gravity is 10 m/s². In order to avoid plane by an angle greater than

Two particles of equal mass are connected to a rope AB of negligible mass such that one is at end A and other dividing the length of rope in the ratio 1 : 2 from B. The rope is rotated about end B in a horizontal plane. Ratio of tensions in the smaller part to the other is (ignore effect of gravity)
