Question

A particle of mass m and charge -q has been projected from ground as shown in the figure below.

Mark out the correct statements (s) :-

• A. The path of motion of the particle can be parabolic
• B. The path of motion of the particle can be straight line
• C. Time of flight of particle is $\frac{2u \sin \theta}{g}$
• D. Range of motion of the particle will be less than $\frac{u^2 \sin 2\theta}{g}$

Answer 1

Answer: (A)

The path of motion of the particle can be parabolic

Answer 2

The path of motion under constant acceleration is a parabola unless the initial velocity is parallel to the acceleration. In the general case, the initial velocity is not parallel to the acceleration, so the path is parabolic. Thus, the path can be parabolic.
