The proton travels before reaching its turning point .

See the step by step solution

Step by Step Solution

Step 1 : Given information and formula used

Given :

The surface charge density on the infinite charged plane :

Proton shot straight away at the speed :

Theory used :

The Electric field owing to an infinite plane is calculated as follows:

Newton's law :

Step 2 : Calculating how far the proton travels before reaching its turning point 

Due to the action of the infinite plane's electric field, this proton will come to a halt before returning. We can compute the distance it goes before turning back using conservation of energy :
