A body at rest breaks up into three parts. If two parts having equal masses, flyr off perpendicularly, to each with a speed of `12ms^(-1)`. The mass of the tird fragment is thrice the mass of the each of the other fragments, then

Options

A. the speed of the third fragment is `6sqrt(2)ms^(-1)`
B. the speed of the third fragment is `4sqrt(2)ms^(-1)`
C. the direction of motion of the third fragment is `135^(@)` from the other two
D. the direction of motion of the third fragment is `45^(@)` from one of the fragments

Answer

B, C
