Which statement is true about a body moving at a constant speed in a circle? A. It has no acceleration.
B. It has an acceleration directed radially and outward.
C. It has an acceleration directed radially and inward.
D. It has an acceleration directed tangentially.

B

Explanation:

When something is moving at a constant velocity it's called the centripetal force. And the centripetal force accelerates radially outwards. It's like an ambulance siren. the sound waves are being exerted out into the atmosphere radiallly.

i think the answer is a and b

i wish you luck

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
