"J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup." I looped this up, hoped it helped:)
Option (C) is correct.
A projectile is an object launched at an angle with the horizontal and allowed to move freely under the effect of gravity alone.
Thus the only external force acting on a projectile is the force of gravity.There may be the force of air friction acting but for all practical purposes, we neglect its effect.
Thus only force of gravity acts during projectile motion.

Answer:
The answer is below
Explanation:
We are going to use Gauss’ law to find the electric field equation. Since electric field is coming from an infinite line of charge, hence it is going out in a radial direction.
Therefore we use the area of the electric field which passes through, forming a Gaussian cylinder. We neglect the ends of the area.
Hence:
