Question
Please show work inlcuding formulas used and any explanation you feel necessary.
a. If you know both the magnitude and direction of an electric field at some point in space, than if any point charge with known signs is placed at that point, you may determine both the magnitude and direction of the force on that point charge. True or False? b. A Gaussian Surface surrounds 3 charges. No matter where the charges are placed within the surface, the total electric flux (or lack of) through the (Gaussian surface is always the same. True or False? e. A spherical Gaussian surface of radius R surrounds a point charge and is concentric with it. If this concentric spherical surface is expanded to a radius of 2R, the electric field due to the point charge at 2R is unchanged from its value at a radius R. True or False? d. Consider a dipole p=qd where q is the charge and d is the separation between the charges. At a distance r>>> d. the electric field of the dipole behaves as if the source of the electric field was a point charge. True or False? e. An electric dipole oriented as shown in a uniform electric field is allowed to move freely. Assuming no friction, it will rotate to theta = 0and stop. True or False?Explanation / Answer
a) True
negative charged particel is accelerated opposite to E
positive charged particel is accelerated towards to E
b) True
total flux = Qin/epsilon (so, it it does not depend on oriantation)
c) False
Here flux through the two surface is same. but not E.
d) True
e) Figure is not visible.
P and E will be opposite in direction direction in the equilibrium.
