Acar moves on a circular path of radius 30m with a velocity of 2.5ms if it mass is 20g find its angular speed

r = 30m

v = 2.5 m/s

m = .02kg

v = r*omega

omega = (delta thaeda)/(delta time)

2.5 m/s = 30m*omega

.08333...  = omega

*note, omega stands for angular velocity

Also, it's been a while since I've done a physics problem like this so I could be wrong. I think this is the answer though :)

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
