61Option b
The reason:Let the force applied on the bodies be F
thus,mass of A=F/2(from formula F=ma)while mass of body B =F/5 .Thus the ratio of masses =(F/2)/(F/5)= 2.5/1.Hence the answer is 2.5(option b).
A force produce an acceleration of 2 m/s2 in a body A and 5 m/s2 another body B. Then the ratio of mass of A to the mass of B is
a. 1/(2.5)
b. 2.5
c. 2/(2.5)
d. (3.5)/(2.5)
