Answer:
<em>-2 units of charge</em>
Explanation:
charge on A = Qa = -6 units
charge on B = Qb = 2 units
if the spheres are brought in contact with each other, the resultant charge will be evenly distributed on the spheres when they are finally separated.
charge on each sphere will be =
charge on each sphere = =
= <em>-2 units of charge</em>
Answer:
Radius = 0.8235 cm
Density = 0.7265 g/mL
Explanation:
Given that the volume = 2.34 cm³
The volume of the sphere =
Thus,
<u>r = 0.8235 cm</u>
Volume = 2.34 cm³ = 2.34 mL (1 cm³ = 1 mL)
Mass = 1.7 g
<u>Density = Mass/ Volume = 1.7 g / 2.34 mL = 0.7265 g/mL</u>
