Question

work=force*displacement in dimentional analysis

Answer 1

W=F.S
W=M.A.S (M for mass, A for acceleration, S for displacement)
W=M.S/t.S
So,[W]=[L^2M^1T^-2]

Answer 2

Answer:

Given :-

Force applied = 250 N

Displacement = 3.5 m

To Find :-

Work done in ploughing the length of the field.

Analysis :-

Here. we are given with the force and displacement.

Substitute the given values in the formula of work and get it accordingly.

Solution :-

We know that,

w = Work

s = Displacement

f = Force

Using the formula,

$\underline{\boxed{\sf Work \ done=Force \times Displacement}}$

Given that,

Force (f) = 250 N

Displacement (s) = 3.5 m

Substituting their values,

w = 250 × 3.5

w = 875 J

Therefore, 875 J work is done in ploughing the length of the field.
