Answer:

  • 0 Joules

Explanation:

Given:-

  • Radius of Circular Path ,r = 2 metre.
  • Mass of Body ,m = 1 kg

To Find:-

  • Work Done ,W

Solution:-

Here, we have to calculate the Work done by the body .

As we know that the angle between the speed and displacemet is 90°

Work Done = Fs Cos∅

W = FsCos∅

Where,

  • W denote Work Done
  • F denote Force
  • S denote Displacemet
  • ∅ denote angle between Speed & Displacemet.

Substitute the value we get

→ W = Fs × 0

As Cos90° = 0

→ W = 0

  • Hence, the work done by the body is 0 Joules.

Answer:

Given :-

  • Mass of body (M) = 1 kg
  • Radius of path (R) = 2 m

To Find :-

Work done

Solution :-

As we know that

 \huge \bf \: W = Fs \:  \cos \theta

Here,

W is the work done

F is the Force

S is the Displacement

∅ is the angle between speed and displacement

 \tt \: W = Fs \:  \times 0

As cos 90⁰ = 0

 \tt \: W = 0

Hence :-

The work done by the body is 0 Joule.
