Question

Two bodies A andB of masses 10kg and 15kg respectively kept on a smooth surface are tied to ends of a light string . If T represents the tension in the string when a horizontal force F=500N is applied to A(as shown in fig1,) and T' be the tension when it is applied to B,,(fig) ,then which of the following is true?​

Answer 1

acceleration=a

a=Fnet/m1+m2

=500/10+15

=500/25

=20 m/s^2

for the first case

T=m2*a

=15*20

=300 N

for second case

T'=m1*a

=10*20

=200 N
