A cold soft drink is kept on the balance. When the cap is open, then the weight

A

Increases

B

Decreases

C

First increases then decreases

D

Remains same

Solution

(c)Gas will come out with sufficient speed in forward direction, so reaction of this forward force will change the reading of the spring balance.

One end of a massless spring of spring constant $k$ and natural length $l_{0}$ is fixed while the other end is connected to a small object of mass $m$ lying on a frictionless table. The spring remains horizontal on the table. If the object is made to rotate at an angular velocity $\omega$ about an axis passing through fixed end, then the elongation of the spring will be
