An Inverted Microscope gives you more freedom than an upright microscope. Inverted microscopes are very useful
to examine the surface of heavy and large sized Items
for industrial purposes. Whereas <span>upright microscopes have very limited distance between the table and the objective.</span>
Answer:
Explanation:
Let the charge on bead A be q nC and the charge on bead B be 28nC - qnC
Force F between them
4.8\times10^{-4} = 
=120 x 10⁻⁸ = 9 x q(28 - q ) x 10⁻⁹
133.33 = 28q - q²
q²- 28q +133.33 = 0
It is a quadratic equation , which has two solution
q_A = 21.91 x 10⁻⁹C or q_B = 6.09 x 10⁻⁹ C
