1.	Consider the motion of the tip of the minutes hand of a clock havinga length 'R'.In half an hour itsバDisplacement is 2R3) Displacement is 2R50.2) Distance covered is πR91 Distance covered is 2R
Answer» in half an hour, the tip of minutes hand will be at diametrically opposite point. Displacement is the shortest distance between two points which is the diameter of clock in this case. Hence, the displacement is 2R. Distance travelled will be half the perimeter of clock which is equal to πR .Hence,option (1) and (2) are correct.

Answer»

in half an hour, the tip of minutes hand will be at diametrically opposite point. Displacement is the shortest distance between two points which is the diameter of clock in this case. Hence, the displacement is 2R.

Distance travelled will be half the perimeter of clock which is equal to πR .Hence,option (1) and (2) are correct.
