A mass of 
is tied to the end of a string of length 1m. It is, then, whirled in a vertical circle with a constant speed of 
. Given that 
. At which of the following locations of tension in the string will be 
Text Solution
Verified by ExpertsThe correct answer is:
B
Centrifugal force 
Tension = 70 N (sum of above two forces)
i.e. the mass is at the bottom of the vertical circular path
