A block of mass 0.2 kg is suspended from the ceiling by a light string. A second block of mass 0.3 kg is suspended from the first block through another string. Find the tensions in the two strings. Take `g=10 m/s^2`.

Verified by Experts


Given, g= 10 m/s^2
Now, T-0.3g =0
`rarr T=0.3 g`
` =0.3xx10=3N`
`Now, T_1 (0.3g = 0`
` rarr T_1 = 0.2 g+ T`
` =0.2x10+3=5N`
`:. ` Tension in the two strings are 5 N and 3 N respectively.
