A spherical conductor is on an insulating stand, as shown in the figure below. A negatively charged rod is brought close to the sphere but does not touch the sphere. Which of the following describes the resulting charge on the sphere?.
Why is an electric field measured only by a small test charge? A. so the charge doesn't disturb the field B. because small charges have small momentum C. so its size doesn't nudge the charge to be measured aside D. because an electron always is used as the test charge and electrons are small.
Which of the following statements is/are true regarding the electric field lines? 1. They originate on positive charges and terminate on negative charges Π. Field lines never cross each other The direction of electric field is tangent to the field line at any point in space.
A small positively charged object could be placed in a uniform electric field at position A or position B in the figure. How do the electric forces on the object at the two positions compare?.
The magnitude of the electric force on the object is greater at position A B. The magnitude of the electric force on the object is greater at position B C. There is no electric force on the object at either position A or position B The electric force on the object at D. position A is the same nonzero electric force as that on the object at position B 27. A negative charge -q is placed in a nonuniform electric field as shown in the figure. What is the direction of the electric force on this negative charge?.
