Question

The quantum (elementary quantity) of electric charge is e = 1.602 10-19 C. Because the electric field has the same magnitude anywhere in space at a distance r from the point charge q, we can take E outside the integral: Now what we have left to evaluate is the integral of the differential area over a spherical surface, which is given by. Therefore, we have found from Coulomb's Law for the case of a point charge which is the same as the expression for Gauss's Law in equation 22.15. Which of the following statements is (are) true? Electric field lines point inward toward negative charges. Electric field lines form circles around positive charges. Electric field lines may cross. Electric field lines point outward from positive charges. A positive point charge released from rest will initially accelerate along a tangent to the electric Held line at that point.

Explanation / Answer

a) true

b) false ........field lines are diverging from positive charge

c) false .........Then at the same point we will have two directions of electric field which is not possible

d)true

e) True
