Question 

Find the height from the centre of bowl, the block of mass 1kg leaves from bowl surface. What is the  speed of block at this instant. [ friction between bowl and block is o] R= 9m ; g = 10 m/s² .

Click for Solution

A block is kept at the top of the hemispherical bowl, fricition between the block and bowl is zero so block slides down. Find the angle and velocity of block at which block leaves the surface of bowl?
