A person moves to the East for 200m and then to the South for 500m in 30min. Find: a) the total distance traveled
b) the displacement
c) the average speed in
m/s
d) the average velocity in m/hr

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.

attach the statements so i can answer : )

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.
