An electric field from a charge has a magnitude of 4.5 × 104 n/c at a certain location that points outward. if another charge with a magnitude of −2.0 × 10−6 c is brought near it, what is the strength of the electrostatic force that acts on this charge and how do the two charges behave?
0.09 n; repel each other
−0.09 n; attract each other
−2.3 n; repel each other
2.3 n; attract each other

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
