A positively charged spherical object is placed equidistant between two other identical uncharged spherical objects. How would the charges in the middle sphere be distributed?

The charge in the middle sphere will be distributed by induction.

Explanation: The charge in the middle sphere will be distributed through induction. The ends of the two uncharged bodies develop same charges and mutual attraction occurs. The positive charged body pushes the positive charged of the two uncharged bodies farther away and attracts the negative electrons in them.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
