Question

A boy does a work of 1000J in dragging a sack of rice through a distance of 20cm what is the magnitude a force

Answer 1

Answer:

Given:

A boy does 1000 joules of work in ragging an object through a distance of 20 metres.

To find:

Magnitude of force applied by the boy.

Calculation:

Work done is a scalar quantity represented by the product of force and the distance for which the object has been moved.

Work represents the energy expended by the force in order to move the object.

Work , being a scalar doesn't have any direction, just has magnitude.

So final answer :

Boy pulled the sack with a force of 50 N

Answer 2

Given:

A boy does 1000 joules of work in ragging an object through a distance of 20 metres.

To find:

Magnitude of force applied by the boy.

Calculation:

Work done is a scalar quantity represented by the product of force and the distance for which the object has been moved.

Work represents the energy expended by the force in order to move the object.

Work , being a scalar doesn't have any direction, just has magnitude.

$\sf{work = force \times displacement}$

$\sf{ = > 1000 = force \times 20}$

$\sf{ = > force = \dfrac{1000}{20} }$

$\sf{ = > force = 50 \:N }=$

So final answer :

Boy pulled the sack with a force of 50 N.
