in a popular carnival ride called the centrifuge, shown above, riders stand agianst the inside wall of a large cylinder

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
