Answer:
Explanation:
Tension provides centripetal force in the circular motion . In circular motion work done by force = torque x angle
torque is zero as , centripetal force passes through axis of rotation that is center.
So work done by centripetal force = 0
So work done by tension on M = 0
Answer:
I think it is D
Explanation:
the Bohr model says that electrons whizz around the atomic nucleus in the same way that the earth goes around the sun - but rather than being bound by gravity, it is bound by electromagnetic forces.
The what i don't understand lol
