Answer:

Option (a)

Explanation:

There are two types of forces.

1. Balanced forces: When the number of forces acting on a body, such that the net force on the body is zero, they are called balanced forces. In this situation, the acceleration on the body is zero.

Net force = zero

2. Unbalanced forces: When the number of forces acting on a body, such that the net force acting on the body is non zero, they are called unbalanced forces. In this situation, the acceleration on the body is non zero.

So, the pair of balanced forces acts on an object, this gives always net force acting on the object is zero.

a. equal to zero.
because the forces are balance (equal magnitudes, opposite directions)

What is the force felt by the electrons and the nuclei in the rod when the external field described in the problem introduction

fomenos

Complete Question

The complete question is shown on the uploaded image

Answer:

The nuclei experience a force that will move it to the right of the conductor rod while the electrons experience a force that will move it to the left side of the conductor rod.

Explanation:

The force that act on the charges(both the positive and the negative charge ) is Mathematically expressed as

F = qE => E = F/q

where F is the force, q is the charge and E is the electric field

we can see that the force is directly proportional to the electric field,so an increase in the electric field would increase the force.

we can also see that the electric field is given as force per unit charge and generally the direction of this field is taken to be the direction of the force it would exert on a positive test charge

Now from the question we are being told that the external electric field is the direction of the positive x axis

Hence this field would drive the positive charge i.e the nuclei to the right.

In order to further explain let consider this

Generally the electric field is always radially outward originating from a positive point charge and radially in toward a negative point charge.

what this means for this question, is that the positive point charge is on the left side of the electric field while the negative point charge is at the right side of the field.

According to Coulomb's law which states that unlike term attract while like terms repel, it means that the electron would move to the left of the conductor rod while the nuclei would move to the right side of the conductor rod.
