1.6 Two identical metal spheres, each of mass m and separated by a distance exert a gravitational force of magnitude F on each other. The distand between the spheres is now HALVE D.The magnitude of the force the spheres now exerts on each other is: A y_{2}F B F C 2F D. 4F 相...
Two identical spheres, each of mass m are suspended by vertical strings such that they are in contact with their centres at the same level. A third identical sphere strikes the other two spheres simultaneously with a velocity U such that the centres of the spheres at the instant of impact ...
Severity of impact is generally characterized by the coefficient of restitution. However, influence of material property on the coefficient of restitution has not been clarified yet. The authors previously investigated direct central impacts of two identical spheres in low speed range and revealed that ...
A smooth sphere of mass m strickes it in a direction perpendicular to its inclined face and rebounds. If the coefficient of restitution is e, find the ratio of the speed of the sphere just before and just after the impact. View Solution Knowledge Check Two identical spheres P and I lie...
1.7 Two identical positively charged spheres, which are free to move, are placed near each other on a frictionless surface.Which ONE of the following CORRECTLY describes the motion of the two spheres? A They move away from each other with increasing acceleration. B They move away from each ...
12There is no atmosphere on the Moon.Two metal spheres ofidentical volume but different masses are at the same height above the ground on the Moon. They are released from rest at the same time.How do the spheres move after they are released? C A The sphere with the larger mass has a...

Calculate the force of attraction between two balls each of mass 1 kg when their centers are 10 cm apart. (given G = 6.67 \times 10^{-11} Nm^2K/g^2) What is the force of gravity between two spheres that have a mass of m1 =13 kg, m2 = 49 kg, and a...
Why do like magnetic poles repel each other? What is the origin of this phenomenon? Why do like charges and poles repel, unlike charges and poles attract? Discuss how a ramp would help you to distinguish between two identical looking spheres of the same weight, one solid and the oth...
Prediction of packing configurations of identical objects is in general a tough problem, even for very simple particle geometries and without spatial restrictions. Such problems have a long history. For example, the densest regular three-dimensional (3D) packing of spheres was already conjectured by...
