Question

To create uniform electric field, a capacitor containing two infinitely large plates are used. Particles in column-I are projected horizontally from the middle with same kinetic energy. Neglect force acting between the particle and also neglect gravity. Match the column

Column-I	Column-II
(A) α-particle	(p) Particles which will move along path–(1)
(B) 23Na+1	(q) Particles which will move along path–(2)
(C) 6Li+1	(r) Particles which will strike the negative plate in minimum time
(D) 2D+1	(s) Particles which will strike the negative plate in maximum time
	(t) Particles which will strike the plate with maximum kinetic energy

Answer 1

The Correct option is (A) – p, r, t ; (B) – q, s ; (C) – q ; (D) – q, r

Explanation:

KE = same for all 

⇒ y ∝ q

So particle with greater q, will have greater y

So α-particles will move along path 1 to strike the plate
