As per Coulomb's law we know that force between two charges is given as

F = \frac{kq_1q_2}{r^2}

here we know that

q_1 = 2.5 \times 10^{-6} C

q_2 = -5.0 \times 10^{-6} C

r = 0.0050 m

now from above formula we will have

F = \frac{(9 \times 10^9)(2.5 \times 10^{-6})(5 \times 10^{-6})}{(0.0050)^2}

F = 4500 N

so they will attract towards each other as they are opposite in nature with force F = 4500 N

nlexa [21]

Answer:

ω = 380π rad/s

Explanation:

The formula for the angular frequency is the oscillation frequency f (hertz) multiplied by 2π

ω = 2πf

then

ω = 2π(190)

ω = 380π rad/s
