Question

3. a stone of mass m gram is rotated in a circular path with a uniform speed by tieing a strong string with the help of your hand ? answer the following:-
i)is the stone moving with uniform or variable speed
ii)is the stone moving a uniform acceleration or variable accelertion? in which direction the acceleraton act?

Answer 1

Dear student
according to question
1> stone moves with uniform speed hence its speed remains constant
2> now during circular motion a centripetal acceleration acting along the centre of circle and g downwards but resultant of both in magnitude remains constant but changes its direction
