# From a fixed support two small isentical spheres are suspended by means of strings of length 1m. THe two strings are pulled aside such that string 1 makes an angle of 30 degrees with the vertical and string 2 makes an angle of 6o degrees and then are released.Point "O" is given to be the mean position.Then the two spheres collide
a)at 'O' after 0.25s
b)at 'O'after 0.25s
c)on the right of 'O' after some time
d)on the right hand side of 'O' when the strings are inclined at 15 degrees with the vertical.
