A string breaks if its tension exceeds 10 newtons. A stone of mass 250 gm tied to this string of length 10 cm is rotated in a horizontal circle. The maximum angular velocity of rotation can be
A 500 kg car takes a round turn of radius 50 m with a velocity of 36 km/hr. The centripetal force is
A ball of mass 0.25 kg attached to the end of a string of length 1.96 m is moving in a horizontal circle. The string will break if the tension is more than 25 N. What is the maximum speed with which the ball can be moved
A body of mass 5 kg is moving in a circle of radius \[1\,m\] with an angular velocity of 2 radian/sec. The centripetal force is
If a particle of mass \[m\] is moving in a horizontal circle of radius \[r\] with a centripetal force \[( - k/{r^2})\], the total energy is
A stone of mass of 16 kg is attached to a string 144 m long and is whirled in a horizontal circle. The maximum tension the string can withstand is 16 Newton. The maximum velocity of revolution that can be given to the stone without breaking it, will be
A circular road of radius 1000 m has banking angle \[{45^o}\]. The maximum safe speed of a car having mass 2000 kg will be, if the coefficient of friction between tyre and road is 0.5
