Question

. What will be amount of work done, when a force 35 N displaces a body through 25 m in its own direction

* a) 875 N
b) 875 Pa
c) 875 J
d) 750 J​

Answer 1

Answer:

Explanation:

given:

•force applied = 25N

•displacement = 10m

to find:

•work done.

solution:

since the work done and displacement is along the same direction

(let us assume positive x-axis)

________________

________________

the angle between the two wouldbe 0°.

we will use the formula to calculate work done:

\underline{\underline{\boxed{\red{\tt work=force×displacement}}}}

work=force×displacement

placing values which are known in the above equation,

\tt work=(25)(10)work=(25)(10)

\tt work = 250work=250

SI unit:

•the S.I units of force and distance are Newton and metre respectively

•collectively, the SI unit of work would be Newton metre.

•newton metre is also called as Joule represented as J

so, the work done is :

\boxed{\blue{\tt work = 250J }}

work=250J

hope this helps!!
