Two balls are dropped from the same point after an interval of $1$ s. If $g = 10 m / s^{2}$ , their separation $3$ seconds after the release of the first ball is:

Options:

Answer:

Solution:

In $3$ s the first ball falls $\frac{1}{2} (10) (9) = 45$ m; in $2$ s the second ball falls $\frac{1}{2} (10) (4) = 20$ m. Separation = $45 - 20 = 25$ m. Option C.
