Question

Two ***** of masses M1 and M2 are placed on horizontal frictionless table connected by a spring as shown in figure, how mass M2 is pulled to the right with a force F ? If the acceleration of mass M1 is a, then acceleration of mass M2 will be

(a) F/M1

(b) F-M1a/M2

(c) F/M2

(d) of these

Answer 1

Correct Option (b) F-M1a/M2

Explanation :

For acting on mass M1 is f = M1a. Mass M1 will pull mass M2 towards left with a force F = Maa.Net force acting on mass M2 = F - t = F -M1a Acceleration of mass M2 = F-M1a/M2
