A23.0 kg bucket of water is suspended by a very light rope wrapped around a solid uniform cylinder 0.300 m in diameter with mass 13.0 kg. the cylinder pivots on a frictionless axle through its center. the bucket is released from rest at the top of a well and falls 10.5 m to the water.

The tension in the rope is 49.66 N.

Explanation:

Given that,

Mass of bucket m= 23.0 kg

Diameter = 0.300 m

Mass of rope M= 13.0 kg

Height = 10.5 m

Suppose we need to find the tension in the rope while the bucket is falling.

We need to calculate the acceleration

Using balance equation

..(I)

We need to calculate the tension in the rope

Using formula of tension

....(II)

Put the value of T in the equation (I)

Put the value into the formula

Now, put the value of a in equation (II)

Hence, The tension in the rope is 49.66 N.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
