Linh builds a circuit from the diagram shown. A rectangular box of lines with the long side vertical and an extra horizontal lin
e about 2 thirds of the way up. The top line has a circle with an X in it labeled 1. The right side from top has a top circle 2 with an X in it then the connection with the extra line then a bottom circle 4 with an X in it. The extra line has a circle 3 with an X in it. The left side has a stack of horizontal lines near its bottom, which are, from top very short, short, very short, short. If Linh removes bulb 3, which bulbs will remain lit?

Explanation:
The normal force exerted on the car by the walls of the cylinder at the bottom of the vertical circle will be such that when substracted to the weight it must give the centripetal force, since at that point on the vertical
We also know that the equation for the centripetal force is:
Mixing both equations we get:
Which for our values means:
