A particle revolves round a circular path. The acceleration of the particle is
A satellite has mass m speed v and radius r, the force acting on it is: |
Answer |
A car of mass 1000 kg moves on a circular road with a speed of 20 m/s. Its direction changes by 90° after traveling 628 m on the road. The centripetal force acting on the car is |
Answer |
A motor cyclist moving with a velocity of 75 km/hr on a flat road takes a turn on the road at a point where the radius of curvature of the road is 20 m. If the g is 10 m/s2 the maximum angle of banking with vertical for no skidding is |
Answer |
A simple pendulum of effective length ‘l’ is kept in equilibrium in vertical position. What horizontal velocity should be given to its bob, so that it just completes a vertical circular motion? |
Answer |
A small body attached at the end of an inextensible string completes a vertical circle, then its |
Answer |
A small body is to be moved inside a vertical circular tube of radius l. What minimum velocity should be imparted to it, as its lowest point so that it can just complete the vertical circle? |
Answer |
A stone attached to a rope of length l = 80 cm is rotated with a speed of 240 r.p.m. At the moment when the velocity is directed vertically upwards, the rope breaks. To what height does the stone rise further? |
Answer |
A stone is tied to one end of a string. Holding the other end, the string is whirled in a horizontal plane with progressively increasing speed. It breaks at some speed because |
Answer |
The K.E. (K) of a particle moving along a circle of radius r depends upon the distance covered (s) as K = as2. The centripetal force acting on the particle is given by |
Answer |
A particle moves in a circular path of radius r, in half of its period. Its displacement and distance covered are, |
