Question

-1 points SerCP11 15.00.001 A suspended object A is attracted to a neutral wall. It's aoatracted to a positively charged object B. Which of the following is true about object A? My O It is uncharged O It has a negative charge O It has a positive charge O It may be either charged or uncharged Need Help? Resd -/1 points SerCP11 15.00.002 Object A has a charge of +2 C, and object B has a charge of +6 C. which statement is true? My O FAB =-FBA Need Help? ReadH -/1 points SerCP11 15.00.003 A test charge of +3 C is at a point where the electric field due to the other charges is directed to the right and has a magnitude of 4. x 106 N/C. If the test charge is replaced with a charge of-3 C, what happens to the electric field at P? My O The field increases in magnitude and changes direction. O The field remains the same O The field has the same magnitude as before, but changes direction O The field decreases in magnitude and changes direction Need Help? LRead

Explanation / Answer

1.) A has negative charge. Any charge particle wether it is -ve or +ve, attracted by neutral wall because it induces opposite charge on neutral wall hand hence attraction force exists. now for second case it aslo satisfy because a -ve charge always attracts +ve charge.

2.) third option is correct because both charges are +ve in nature so repulsive forces exists between them.

3.) option 4th is correct: the firld decreases in magnitude and change direction.
