Question

3 blocks of equal masses each 3 kg are suspended by weightless string as shown in fig if applied forces is 100 n

Answer 1

here we need to find the tension in T1

W.K.T

T1=F+mg ---- 1

here, F=100N, m=3kg, g=10m/s^2

substitute the above values in 1

T1=100+(3)(10)

T1=100+30

T1=130N

therefore T1=130N

HOPE IT LOOKS EASY AND SIMPLE.....

THANK YOU :)

Answer 2

Tension= f+m*g

            = 100+3*10

           = 100+30

          = 130 newton(N)
