Two identical billiard balls undergo an oblique elastic collision. Initially, one of the balls is stationary. If the initially stationary ball after collision moves in a direction which makes an angle of with direction of initial motion of the moving ball, then the angle through which initially moving ball will be deflected is |

When two identical balls undergo elastic oblique collisions with one of them stationary, then after collision they will move at right angles to each other
Alternative method I: Just like in previous question, you can proceed using centre of mass frame of reference
Alternative method II: Using basic equations of conservation of momentum, conservation of energy and coefficient of restitution, you can have the desired result
