Questions in Motion in A Plane

Select	Question
	Two bodies of equal masses revolve in circular orbits of radii \[{R_1}\] and \[{R_2}\] with the same period. Their centripetal forces are in the ratio
	In case of uniform circular motion which of the following physical quantity do not remain constant
	What happens to the centripetal acceleration of a revolving body if you double the orbital speed \[v\] and half the angular velocity \[\omega \]
	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 \[{\omega _0}\]. If the length of the string and angular velocity are doubled, the tension in the string which was initially \[{T_0}\] is now
	In 1.0 s, a particle goes from point A to point B, moving in a semicircle of radius 1.0 m (see figure). The magnitude of the average velocity is
	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 $v_0$, then the ratio of tensions in the three sections of the string is
	A particle is moving in a circle of radius R with constant speed v, if radius is double then its centripetal force to keep the same speed should be
	A stone ties to the end of a string \[1m\] long is whirled in a horizontal circle with a constant speed. If the stone makes 22 revolution in 44 seconds, what is the magnitude and direction of acceleration of the stone
	A particle describes a horizontal circle in a conical funnel whose inner surface is smooth with speed of 0.5 m/s. What is the height of the plane of circle from vertex of the funnel ?
	What is the angular velocity of earth
