Question

A body of mass 0.5 kg is whirled in a verticle circle of radius 0.5 m with an angular frequency 10 rad/sec find the tension at the lowest point...​

Answer 1

⇒ GIVEN :-

• A body of mass 0.5 kg is whirled in a verticle circle of radius 0.5 m with an angular frequency 10 rad/sec find the tension at the lowest point

⇒ SOLUTION :-

We know that,

• tension in the string when the body is at the top T = Centrifugal force - gravitational force

so,

m × square of angular velocity × radius - m × g

• = 0.5 × 10 × 10 × 0.5 - 0.5 × 10
• = 25 - 5
• = 20 N

⇒ FINAL ANSWER :-

$\huge \red \star \: \huge\boxed{ \implies \sf{20 \:N} }$
