A, B, C and D are four masses each of mass m lying on the vertices of a square of side ‘a’. They always move along a common circle with velocity v. Find v so that they always remain on the vertices of the square.
|F 1 | = |F 2 | so, 
= 
F 1
A
B
C
D
None
Text Solution
Verified by ExpertsThe correct answer is:
A
F net = √ √ 2 F 1 + F 2 = 
a = 2R or R = 
or v =
