Question

an object of mass 5 kg is whirled around in a vertical circle of radius R with a constant speed of 6 the maximum tension in the string is​

Answer 1

Explanation:

The maximum tension is created at bottom point

at that point draw the FBD

we get

T-mg=mv^2/R

T=mv^2+mg

put the values and get the ans

Answer 2

Explanation:

• So there is a path in which there is a vertical circular motion. So the tension is maximum at the lowest position and the centrifugal force is outwards and mg force that is acceleration due to gravity will be downwards, also the tension is upwards.
• So mass m = 5 kg
• Radius r = 2 m
• Speed v = 6 m/s
• Now tension = centrifugal force + mg force
• So T = fg + mg
•         = mv^2 / R + mg
•         = 5 x 6 x 6 / 2 + 5 x 9.8
•         = 90 + 49
•     T = 139 N
