Problem 42P

CE Two electric charges are separated by a finite distance. Somewhere between the charges, on the line connecting them, the net electric field they produce is zero, (a) Do the charges have the same or opposite signs? Explain, (b) If the point of zero field is closer to charge 1, is the magnitude of charge 1 greater than or less than the magnitude of charge 2? Explain.

Step-by-Step Solution:

Solution 42P

Step 1 of 3 </p>

(a)

Here we need to comment whether charges should have same or opposite signs, in order to have net electric field as zero between the charges on the line joining two charges.

When both the charge are of same sign, the equilibrium or zero net field point can exist between the two charges on the line joining charges, as shown in the figure below.

Where is force exerted by the charge 1 on charge , is charge force by the charge 2 on charge

Step 2 of 3</p>

(b)

When the zero electric field is near to the charge 1, we need to explain whether the magnitude of charge 1 will be greater than or lesser than that of the magnitude of charge 2.

The force exerted by charge 1 as well by charge 2 must be equal in magnitude at zero field point as shown in the figure below.
