Coach's note
Name the force behind the circle
Your radial direction is secure. The next gain is identifying which real interaction supplies the centripetal force.
- Direction — You consistently point acceleration towards the centre.
- Force source — The magnetic or gravitational force was not named explicitly.
Replace “centripetal force” with the actual force before calculating.
One cross-topic fields problem should secure that link.
Latest marks & feedback
