A body of mass $$5 \times 10^3 \mathrm{~kg}$$ moving with speed $$2 \mathrm{~m} / \mathrm{s}$$ collides with a body of mass $$15 \times 10^3 \mathrm{~...

Assertion : There is no loss in energy in elastic collision. Reason : Linear momentum is conserved in elastic collision.

Assertion : Even though net external force on a body is zero, momentum need not to conserved. Reason : The internal interaction between particles of a...
