If one end of the massless rope passing through pulley fixed on top of the roof is connected to 50 kg block and another end to a fixed point below the ground as shown below, then what will be the tension on the string?

If one end of the massless rope passing through pulley fixed on top of the roof is connected to 50 kg block and another end to a fixed point below the ground as shown below, then what will be the tension on the string? Correct Answer 500 N

Concept:

• Force: It is a kind of push or pulls applied to an object which causes it to accelerate at a certain rate
• i.e., Force produces acceleration in a body.

∴ F = m × a

• A simple machine that uses wheel and rope to lift a heavy load is called a pulley system
• Pulley: It is a simple wooden or metallic machine that uses the wheel and rope to lift heavy loads.
• Tension: The tension force is defined as the force that is transmitted through a rope, string, or wire when pulled by forces acting from opposite sides.
• Mass: It is the measure of the amount of matter in a body. The SI unit of mass is kilogram (kg)
• Weight: It is the measure of the force of gravity acting on a body.

And the weight of the body is given as,

Weight of body (W) = mass (m)× acceleration due to gravity (g)

Here,

Mass of object/body = m

Rate of acceleration = a

Acceleration due to gravity = g

Force acting on object = F

Explanation:

As per the given condition

if one end of the massless rope passing through pulley is connected to 50 kg block and another end to a fixed point below the ground such case the tension on the string will only be because of this 50 kg mass

 Thus, tension on the string will be equal to the weight of the block

∴ T = Weight = mg

Here mass is 50 kg whereas consider acceleration due to gravity (g) be 10 m/s²

Hence tension on the string will be approximately 500 N, which means only option A is correct among all.
