its period of revolution is 
.
. B
the tension in the string is double the weight of the particle
C
the speed of the particle 
D
the centripetal acceleration of the particle is 
.
.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a,b,c,d):
= 
........
= mg .......
Hence T = 2 mg , So holds
From & V 2 = 3 g λ /2
∴ V = 
∴ V = 2.8 
m/s. So hold
a c = V 2 /r = 
= 
× g = 9.8 
m/s 2
∴ holds
t = 
= 
t = 4 π /7 ∴ holds.
