Question

Three blocks are connected to each other with light inextensible strings as shown in the figure. Tension T1 and T2 are respectively?

Answer 1

For block of mass 3kg force

= T1-20=3a......... 1

For block of mass 7kg

Force , = T2-T1=7a..........2

For block of mass 10kg force

= 100-T2=10a

Solving three eqn a=4

T1=20+12=32N

T2=60N

Answer 2

Answer:

T1 = 32

T2 = 60
