Question

A box is pulled with 25 Newton to produce a displacement of 15 metre if the

angle between the force and displacement is 30 degree find the work done?​

Answer 1

Given:-

• Force applied on box = 25N

• Displacement of box = 15m

• angle between F and S = Cos 30° = √3/2

To Find:-

• The Work Done

Formulae used :-

• Work Done = F × S × Cos ∅

Now,

→ Work Done = F × S × Cos ∅

→ Work Done = 25 × 15 × Cos 30°

→ Work Done = 375 × √3/2

→ Work Done = 324.759J

Hence, The work done on Box is 324.759J.

Answer 2

Answer:

Given:-

⇒ Force applied on box = 25N

⇒ Displacement of box = 15m

angle between F and S = Cos 30° = √3/2

To Find:-

The Work Done

Formulae used :-

Work Done = F × S × Cos ∅

Now,

→ Work Done = F × S × Cos ∅

→ Work Done = 25 × 15 × Cos 30°

→ Work Done = 375 × √3/2

→ Work Done = 324.759J

Hence, The work done on Box is 324.759J.
