Question Completion Status QUESTION 11 1 points The lighter particles such as atoms and molecules are subjected to the electrostatic potential energy. which is given by the following equation Eel-k(Q1 x Q2) / d k-8.99x10-9 jm/c2 If a proton (Q1-1.6x 10-19 C) and an electron (-1.6x10-19 C) are placed within 5 pm (picometers) to each other what will be the force between the two particles? Would it be attractive or repulsive? 4.602X10-35yt Force is attractive 2.876X10 16jJ: Force is repulsive 4.602x10 35J: Force is repulsive 2.876x1016 ;: Force is attractive 2.301 x 1046J: Force is attractive QUESTION 12 1 points

Explanation / Answer

Ans : A) 4.602 x 10-35 J ; Force is attractive

Since the particles are of opposite charges i.e. proton and electron , the forces present in between them will be attractive and not repulsive.

By putting all the values in the formula mentioned in the picture , we get :

E = (8.99 x 10-9 x 1.6 x 10-19 x -1.6 x 10-19) / (5 x 10-12)

= 4.602 x 10-35 J
