Question

Statement -1 : A rain drop after fallling through some height attains a constant velocity.
Statement -2 : At constant velocity, the viscous drag is just to its weight.
A. Statement -1 is true , Statement -2 is true , Statement -2 is a correct explanation of Statement -1.
B. Statement -1 is true , Statement -2 is true , Statement -2 is not a correct explanation of Statement -1.
