A particle of unit mass undergoes one-dimensional motion such that its velocity varies according to $$v\left( x \right) = \beta {x^{ - 2n}}$$, where $$\beta$$ and n are constants and x is the position of the particle. The acceleration of the particle as a function of x, is given by
A
$$- 2{\beta ^2}{x^{ - 2n + 1}}$$
B
$$- 2n{\beta ^2}{e^{ - 4n + 1}}$$
C
$$- 2n{\beta ^2}{x^{ - 2n - 1}}$$
D
$$- 2n{\beta ^2}{x^{ - 4n - 1}}$$

The displacement 'x' (in meter) of a particle of mass 'm' (in kg) moving in one dimension under the action of a force, is related to time 't' (in sec) by t = $$\sqrt x + 3$$. The displacement of the particle when its velocity is zero, will be
A
4 m
B
0 m (zero)
C
6 m
D
2 m

A stone falls freely under gravity. It covers distances h1, h2 and h3 in the first 5 seconds, the next 5 seconds and the next 5 seconds respectively. The relation between h1, h2 and h3 is
A
h2 = 3h1 and h3 = 3h2
B
h1 = h2 = h3
C
h1 = 2h2 = 3h3
D
$${h_1}$$ = $${{{h_2}} \over 3}$$ = $${{{h_3}} \over 5}$$
