The Attempt at a Solution
## α = v\frac{dv}{ds} ## and K is the kinetic energy .
In all the four cases ## α = v\frac{dv}{ds} = mgsinθ ## where θ is the angle which the normal to the body makes with the vertical .
Fig 1) K increases and tangential acceleration α decreases ,so matches with P)
Fig 2) K decreases and tangential acceleration α also decreases ,so matches with S)
Fig 3) K increases and tangential acceleration α also increases ,so matches with R)
Fig 4) K decreases and tangential acceleration α increases ,so matches with Q)
According to me the correct option is (C)
Is this the correct option ?
Many thanks
