Two charged objects, A and B, are exerting an electric force on each other. What will happen if the charge on A is increased? А. The charge on B will decrease.

B. The charge on B will increase.

C. The electric force between A and B will decrease.

D. The electric force between A and B will increase.​

If the charge on A increases, the force on BOTH objects will increase.

The electric force between two charges is always equal in both directions, just like the gravitational force between two masses.

So I guess choice-B  and choice-D  are both correct.  

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
