Two bodies A and B of masses 10kg and 15kg respectively kept on a smooth, horizontal surface are tied to the 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 figure 1) and T' be the tension when it is applied to B (figure2), then which of the following is true?

Options

A. T=T=500N
B. T=T=250N
C. T=200N,T=300N
D. T=300N,T=200N

Answer

D

Explanation

Acceleration `=(500)/(25)=20 m//s^(2)` in both the cases.
In fig1, `T=500-10xx20=300N`
In fig 2, `T=500-15xx20=200N`.
