A cannon after firing recoils due to
(1) greater than velocity of body A
(2) greater than velocity of body B
(3) less than the velocity of body A
(4) less than the velocity of body B
All options are correct :
(i) When two bodies A & B move in opposite directions then relative velocity between A & B either vAB or vBA both are greater than vA & vB.
(ii) When two bodies A & B move in parallel direction
then vAB= vA–vB ⇒ vAB < vA
vBA=vB–vA ⇒ vBA < vB
