Question

One end of spring of length l is connected to a particle of mass 'm' and the another end is connected to a small peg on a smooth horizontal table. If the particle move in circle with speed 'v' the net force on the particle ( directed towards centre) will be (T represents the tension in the string). km​

Answer 1

Answer:

please mark my answer a branlest

Explanation:

We know,

When, a particle tied with sting and moves in circular, the required centripital

force tension in string

Here length of string 'I ' is connected to a particle of mass m. after moving of string in a circle with speed v.

Centripital force = mv²/l directed towards the centre. and tension in string is T

Hence, net Force of string

directed towards centre = centripital force Tension in string

e.g T

= mv²/1

hence, correct alternative is T
