Question

When calculating the electric field of an object with electric charge distributed approximately uniformly over its surface, what is the order in which you should do the following operations? (1) Check the direction and units. (2) Write an expression for the electric field due to one point-like piece of the object. (3) Divide up the object into small pieces of a shape whose field is known. (4) Sum the vector contributions of all the pieces.

Short answer

Answer

The order of doing the following operation is (3)-(2)-(4)-(1).

Step-by-step solution

Significance of an electric charge

The electric charge is described as the physical property of a matter that helps to induce a force when placed inside a particular electromagnetic field. There are two types of the electric charges mainly positive and negative charges.

Determination of the right order of doing the operations

The first and the foremost step for calculating the electric field of an object is to divide the objects into small pieces whose electric field is known. The second step write the expression of the electric field of that object. The third step is adding the vector contributions of the pieces. The final step is to checking the units and directions in order to check the results.

Thus, the order of doing the following operation is (3)-(2)-(4)-(1).
