Question

a string of length l has one fixed end and a particle of mass m attached to the other end travels in a horizontal circle of radius r. the tension in the string is​

Answer 1

Answer:

☆Solution:

》First see the attachment for visual.!

》motion called as horizontal circular motion.

》because of centripetal force present the particle is doing a circular motion.

》centripetal force is nothing, but provided by existing external force.

》only tension is present as an external force which will provide the centripetal force.

》Tension = centripetal force

》T = m$\ { \omega ^{2}}$r

》T = m$\bold{ \omega ^{2}}$l
