A particle of mass m is moving in the xy-plane such that its velocity at a point (x,y) is given as `vec v` = `alpha(y hat x + 2xhaty)` where `alpha` is a non-zero constant. What is the force `vec F` acting on the particle?

A

`vecF`=2m`alpha^2`(x`hatx` + y`haty`)

B

`vecF`=m`alpha^2`(y`hatx` + 2x`haty`)

C

`vecF`=2m`alpha^2`(y`hatx` + x`haty`)

D

`vecF`=m`alpha^2`(x`hatx` + 2y`haty`)

Path traced by a moving particle in space is called trajectory of the particle. Shape of trajectiry is decided by the forces acting on the particle. When a coordinate system is associated with a particle motion, the curve equation in which the particle moves [y=f(x)] is called equation of trajectory. It is just giving us the relation among x and y coordinates of the particle i.e. the locus of particle. To find equation of trajectory of a particle, find first x and y coordinates of the particle as a function of time eliminate the time factor.
