Brendan drew a diagram to illustrate the centripetal force acting on a satellite.
How can Brendan correct his diagram?

A. Draw the Fg = Fc vector so it points at a 45° angle from the v vector.
B. Change the Fg = Fc vector label so it reads Fa = Fc.
C. Draw the Fg = Fc vector so it is longer than the v vector.
D. Change the Fg = Fc vector so it is perpendicular to the v vector.

Brendan drew a diagram to illustrate the centripetal force acting on a satellite.  

How can Brendan correct his diagram?

Draw the Fg = Fc vector so it points at a 45° angle from the v vector.  

Change the Fg = Fc vector label so it reads Fa = Fc.

Draw the Fg = Fc vector so it is longer than the v vector.  

Change the Fg = Fc vector so it is perpendicular to the v vector.



D is the answer

Answer:

Change the Fg = Fc vector so it is perpendicular to the v vector.

Explanation:

Brendan drew a diagram to illustrate the centripetal force acting on a satellite.   When satellite rotates around a earth, the centripetal force is balanced by gravitational force such that,

[tex]\dfrac{mv^2}{r}=G\dfrac{Mm}{r^2}[/tex]

Centripetal force is a type of force which is responsible for the motion of an object in a circular path. It is a center seeking force. If the centripetal force is absent, the satellite would move in a straight line. It is perpendicular to the velocity of satellite.

Hence, the correct option is (d) "Change the Fg = Fc vector so it is perpendicular to the v vector".
