An object starts from rest at point F and speeds up continuously as it moves around an oval. a. Choose a point about 1/8 th of the way around the oval from point F, and label it point G. Draw a vector to represent the velocity of the object at point G. b. Determine the change in velocity vector  between points F and G.

a) Check the file attached below for the diagram

b) Change in velocity vector between F and G,  

Explanation:

a) The diagram that represents the description is contained in the file attached to this solution. A vector, that represents the velocity of the object at point G is also indicated.

A very good point to note is that the direction of the velocity is always acting tangent to the path

b) The change in velocity vector between F and G

The change in velocity vector is

Since the object starts from rest at point F,

Therefore, Change in velocity vector between F and G,

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
