Two tiny beads are 25 cm apart with no other charged objects or fields present. Bead A has a net charge of magnitude 10 nC and b

Alona [7]

Answer:

E. The force on A is exactly equal to the force on B.

Explanation:

The force between two charges is given by

$F=\dfrac{kq_1q_2}{r^2}$

where

$q_1$ = Charge on particle 1

$q_2$ = Charge on particle 2

r = Distance between the charges

k = Coulomb constant = $8.99\times 10^{9}\ Nm^2/C^2$

$F=\dfrac{8.99\times 10^9\times 10\times 10^{-9}\times 1\times 10^{-9}}{(25\times 10^{-2})^2}\\\Rightarrow F=0.0000014384\ N$

This force will be exerted on both the charges equally.

So, The force on A is exactly equal to the force on B

bazaltina [42]

Answer:

80 N

Explanation:

For A + B: the net force is 100 N = (mA + mB)*a

a = 100/(20 + 5) = 100/25 = 4 m/s²

For A, the net force = mA * a = 20 * 4 = 80 N
