Question: Two uniform similar discs roll down two inclined planes of length S and 2S respectively as shown is the fig. The velocities of two discs at the points A and B of the inclined planes are related as

1) v1 = v2

2) ${{v}_{1}}=2{{v}_{2}}$

3) ${{v}_{1}}={{v}_{1}}\frac{{{v}_{2}}}{4}$

4) ${{v}_{1}}=\frac{3}{4}{{v}_{2}}$
