A particle P will be equilibrium (w.r.t. bowl) inside a hemispherical bowl of radius 0.5 m at a height 0.2 m from the bottom when the bowl is rotated at an angular speed (g = 10 m/sec 2 )-
A
B
C
10 rad/sec
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Ncosθ = mω 2 .r ....(i)
Nsinθ = mg ....(ii)
tanθ = 
= 
from (i) & (ii)
tanθ = 
ω 2 = 
= 
= 
ω =
