Study the following graph:

The particle has negative acceletation.

Options

A. In graph (i)
B. In graph (ii)
C. In graph (ii)
D. In graph (iv)

Answer

C

Explanation

(1). For the graph (i) and (iv) slope is constant hence the velocity is constant.
(2). For the graph (iii), the particle's velocity first decreases and then increases in negative direction. It means negative acceleration in involved in this motion.
