Question

Point charges Q1 = 1 nC and Q2 = 2 nC are at a distance apart. Which of the following

statements are incorrect?

Select one or more:

As the distance between them decreases, the force on Q1 increases linearly.

The force on Q2 is the same in magnitude and direction as that on Q1.

The force on Q2 is along the line joining them.

A point charge Q3 = -3 nC located at the midpoint between Q1 and Q2, Q3 will receive

no net force.

The force on Q1 is attractive.

Answer 1

Coulomb's law states that the electrical forcebetween two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.

F= Kq1*q2/r^2

Hence from formula ekeelect force is vary linearly with distance between the charges.

Electricforce always act between the line joining the charges

So. In question

Statement 2 and 3 are correct

And statement 1,4 and 5 are incorrect.

In this case force will be repulsive nature because both are positive charges
