Two 10-kilogram boxes are connected by a massless string that passes over a massless frictionless. what is tension in the string

The tension in the string is 87.72 N.

Explanation:

Given that,

Mass of two each boxes = 10 kg

Suppose the inclined plane makes an angle is 60° with the horizontal and the coefficient of kinetic friction between the box and plane is 0.15.

We need to calculate the acceleration

Using balance equation

Put the value into the formula

....(I)

Again using balance equation

Put the value into the formula

...(II)

From equation (I) and (II)

Put the value of acceleration in equation (I)

Hence, The tension in the string is 87.72 N.
