Let the acceleration of both rope and block be $a$ .

Let the tension that is exerted between block and rope at the interface be $T$ .

Hence from free body diagram of both block and rope, we have

$F-T=ma$
and $T=Ma$

$\implies$ Force exerted on the block $=T=\dfrac{MF}{M+m}$

A thermometer reads the temperature in a room.On the other hand, a thermostat regulates the temperature. It helps control the temperature in the room by making small adjustments to heat or cool the room. If it gets too cold in the room, the thermostat adjusts and warms it up. If it gets too hot in the room, the thermostat adjusts and cools it down.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
