Question

Part A, B, and C

A sphere with a charge of -50.2 muC is embedded in the electric field shown, which has a magnitude of 1.220 times 10^3 N/C. Answer the three questions below, using three significant figures. Part A: Pick the letter that best describes the direction of force exerted on the charge by the electric field. A B c D Part B: What is the magnitude of force (F) exerted on the charge by the field? F = Part C: How many electrons (N_e) were transfered to the charged sphere in order to obtain the charge specified?

Explanation / Answer

Part A) the negative electric charge move in the oppositive direction of the elctric field. then the letter is D

Part b) the electric force is

F = q E = ( 52.2x10-6 C ) ( 1.22x103 N/C ) = 0.0637 N

Part c)

q = n e ---> n = q / e = ( -52.2x10-6 C ) / ( -1.60x10-19 C ) = 3.26x1014
