... 16. Statement (1) is correct because an alpha source would produce a lot of ion pairs, therefore the ions would neutralize the charges of the spheres, as a result, the spheres become neutral shortly and fall down due to gravity. Statement (2) is correct because the force acting on A is of the same m ...

... A racing car travels on a track (without banking) ABCDEFA (Fig. 5.10). ABC is a circular arc of radius 2 R. CD and FA are straight paths of length R and DEF is a circular arc of radius R = 100 m. The co-effecient of friction on the road is µ = 0.1. The maximum speed of the car is 50 m s–1. Find the ...

... Sample Problem – 3rd Law • A tug-of-war team ties a rope to a tree and pulls hard horizontally to create a tension of 30,000 N in the rope. Suppose the team pulls equally hard when, instead of a tree, the other end of the rope is being pulled by another tug-of-war team such that no movement occurs. ...
