Answer 1

$\large{\mathtt{\red{\underbrace{\overbrace{\blue{\boxed{\boxed{\pink{«Answer»}}}}}}}}}$

Given:-

• Mass of Object = 2kg

• Force applied = 80N
• Distance travelled = 10m

To Find:-

• The work Done by body.

• The work Done by force of gravity.

Formulae used:-

w = F × s

Where,

F = Force

s = Distance

w = Work Done

Now,

→ w = F × s

→ w = 80 × 10

→ w = 800J

Hence, The work done is 800J

→ The work done by force of gravity is zero because force act perpendicular to the displacement.
