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
Here,
W is the work done
F is the Force
S is the Displacement
∅ is the angle between speed and displacement
As cos 90⁰ = 0
Hence :-
The work done by the body is 0 Joule.
