An object moves along the circle with normal acceleration proportional to , where is the time and is a positive constant. The power developed by all the forces acting on the object will have time dependence proportional to
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Given, Normal acceleration =tα We know, acceleration =an=v2R=tα ∴ ν2=tαR K.E=12 mv2=m2tαR ⇒P=ddtK.E=ddtm2tαR ⇒P=mR2αtα-1 ∴ P∝tα-1
