A particle of mass m & charge -q has been projected. In region of uniform electric field E, from ground as shown in fig. Mark the correct statements (x is horizontal & y is vertical) 

 

Along X axis $u_x=u\cos \theta ,a_x=-\frac{qE}{m}$

Along y axis $u_y=u\sin \theta ,a_y=-g$

Equation of motions along x & y axis would be 

$x=u\cos \theta xt-\frac{qE}{2m}{t}^2\mathrm{\&}y=u\sin \theta t-\frac{1}{2}g{t}^2$

Solving above equation we get equation of the form Ax + By = Ct Which is a linear equation Time of flight remains unchanged as vertical motion is not affected by E . 

Range will be less than $\frac{u^2}{g}\sin 2\theta$
