A long plank P of mass 5 kg is placed on a smooth floor On P

A long plank P of mass 5 kg is placed on a smooth floor On P is placed a block Q of mass 2 kg The coefficient of friction between P and Q is 0 5 A horizontal force of 15N is applied to Q as shown in figure and you may take g as 10 N kg Now A the reaction force on Q due to P is 10N B the acceleration of Q relative to P is 2 5 m s C the acceleration of P relative to the floor is 2 0 m s D the acceleration of centre of mass of P Q system relative to the floor is 15 7 O
