Uniform ring of radius R is moving on a horizontal surface with speed v and then climbs up a ramp of inclination 30^ to a hcight h . Thcre is no slipping in the cntirc motion. Then h is
Options
- Av ² / 2 ~g
- Bv ² / g
- C3 v ² / 2 ~g
- D2 v ² / g
Correct answer
B. v ² / g
Step-by-step solution
Using conservation of energy) array l 1 2 mV ²+ 1 2 mR ² ( V R )²= mgh m ( V ² 2 + V ² 2 )= mgh h = V ² ~g array
