Body P of mass m1 is moving on a circular path of radius r1 and body Q of mass m2 is moving on a circular path of radius r2. Both the bodies are moving with the same velocity, V. Under which of the following conditions is the centripetal force acting on the body P DEFINITELY greater than that acting on the body Q? i) if m1> m2 and r1 = r2 ii) if m1 = m2 and r1 > r2 iii) if m1 > m2 and r1 < r2 1 only i 2 only i and ii 3 only i and iii 4 all - i, ii and iii

Answer:
Centripetal acceleration, a
c
=k
2
rt

where, a
c
=
r
v

⇒
r
v

=k

rt

⇒v=krt ........(1)
Tangential acceleration, a
t
=
dt
dv
=kr.........(2)
Tangential force acting on the particle, F=ma
t
=mkr
Power delivered, P=
F
.
v
=Fvcosθ
∴ P=Fv=(mkr)×krt (∵θ=0
o
)
⟹P=mk
