Question
A solid sphere of mass 0.1 kg and radius 2 cm rolls down an inclined plane 1.4m in length at an angle whose slope is 1/10. If sphere started from rest, its final velocity will be
Answer: Option A
:
A
v=√2gh1+k2R2=√2×9.8×lsinθ1+25[Ask2R2=25,l=hsinθandsinθ=110given]
⇒v=√2×9.8×1.4×11075=1.4m/s.
