A particle while sliding down a smooth
plane of 
m length acquires a velocity of 19.86 m/sec. The inclination
of plane is
एक कण m लंबाई के चिकने तल पर फिसलते समय 19.86 m/sec का वेग प्राप्त करता है। समतल का झुकाव है
300
450
600
750
450
Given :Distance traveled (s) m
Final velocity (v) =19.86m/s
From free body diagram,
Hence, the correct option is (B).
