An object of mass 
is attached to the end of a metal wire of unstretched length 
. The object is then whirled in a vertical circle with an angular velocity of 
at the bottom of the circle. If the cross sectional area of the wire is 
and Young's modulus of metal is 
, then the elongation of the wire when the mass is at the lowest point of its path (Take 
)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
When the mass is placed at the position of the vertical circle the force on the mass is F
The elongation of the wire,
