A ring attached with a light spring is fitted in a smooth rod. The spring is fixed at the outer end of the rod. The mass of the ring is 3kg & spring constant of spring is 300 N/m. The ring is given a velocity ‘V’ towards the outer end of the rod and the rod is set to be rotating with an angular velocity ω. Then ring will move with constant speed with respect to the rod if :- a)angular velocity of rod is increased continuously
- b)ω = 10 rad/s
- c)angular velocity of rod is decreased continuously
- d)constant velocity of ring is not possible
Correct answer is option 'B'. Can you explain this answer?

A uniform rod of density ρ, and length ‘l’ is having square cross-section of side ‘a’. It is placed in a liquid of equal density ρ vertically along length in a tank having sufficient height of liquid. The surface tension of liquid is ‘T’ and angle of contact is 120º. Then :- a)rod will float completely immersed inside the liquid
- b)rod will sink to bottom of the tank
- c)rod will float partially submerged with height
above liquid. - d)rod will float partially submerged with height
above liquid.
Correct answer is option 'D'. Can you explain this answer?
