What happens when a negatively charged object A is brought near a neutral object B? OA.
Object B gets a negative charge.
OB.
Object B gets a positive charge.
O c. Object B stays neutral but becomes polarized.
OD
Object A gets a positive charge.
OE.
Object A loses all its charge.

Which of the following changes will increase the capacitance of a parallel-plate capacitor? (there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates

Which of the following best describes the circuit shown below?

Determine the moment of the force f about an axis extending between a and c. express the result as a cartesian vector. a is at the origin, c is at (4,3,0) and f = (4i + 12j -3k) lb coming out of b (4,3,-2).
