Suppose a particle moves along a curve shown by the thick line and the positions of particle are represented by `P` at `t` and `P'` at `t'`.
where, coordinates of P is `(4, 3) and P' is (7, 6)`. Net displacement of the particle will be
Options:
(a) zero
(b) `7hati + 9hatj`
(c) `10hati +18hatj`
(d) `3hati + 3hatj`
