Which motion map represents an object moving in uniform circular motion with the greatest tangential speed?

B since theyre all equal

Answer : Figure B shows maximum tangential speed.

Explanation :

When a body is moving in a circular path of radius r and angular velocity , then its tangential speed is given by :

or it can also defined as :

In circular motion distance covered by particle is,

and if t is the time.

So,

In circular motion the object moves tangentially and the magnitude of tangential speed is same in all direction.

So, figure (B) shows the greatest tangential speed.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
