the process of charging a conductor by bringing it near another charged object and then grounding the conductor is called...

a) charging by contact
b) induction
c) charging by polarization
d) neutralization

which one of the following statements is true concerning the madnitude of the electrical field at a point in space?

a) it is a measure of the total charge of the object
b) it is a measure of the electric force on any charged object
c) it is a measure of the ratio of the charge on an object to its mass
d)it is a measure of the electric force per unit mass on a test charge
e) it is a measure of the electric force per unit charge on a test charge?

The process of charging a conductor by bringing it near another charged object and then grounding the conductor is called induction. This process involves the redistribution of charges within the conductor without direct contact with the charged object.

Now, let's move on to the second question about the magnitude of the electrical field at a point in space. To determine the correct statement, let's go through the options one by one:

a) It is a measure of the total charge of the object. This statement is not true. The electrical field at a point in space depends on the distribution of charges, not the total charge of the object.

b) It is a measure of the electric force on any charged object. This statement is also not true. The electrical field at a point in space indicates the force experienced by a charged object placed at that point, but it's not a direct measure of the electric force.

c) It is a measure of the ratio of the charge on an object to its mass. This statement is not true. The electrical field is independent of the mass of an object and only depends on the charge distribution.

d) It is a measure of the electric force per unit mass on a test charge. This statement is incorrect as well. The electric field is not related to the mass of a test charge.

e) It is a measure of the electric force per unit charge on a test charge. This statement is true. The electrical field at a point in space is defined as the electric force experienced by a positive test charge placed at that point, divided by the magnitude of the test charge. Therefore, it is a measure of the electric force per unit charge on a test charge.

So, the correct answer is option e) it is a measure of the electric force per unit charge on a test charge.
