The form of Coulomb’as+4+h)o lstls law is very similar to that for Newton’s law ofi;s.y vx 8x mdb jaub.55nn)z* universal gravitation. Wh8zndn) . jmsubx;y *vx.i5b a5at are the differences between these two laws? Compare also gravitational mass and electric charge.
参考答案:
The magnitude of the
constant in Newton’s
law is very small, while the magnitude of the constant in Coulomb’s law is
quite large. Newton’s law says the gravitational force is
proportional to the product of the two masses, while Coulomb’s law says the
electrical force is proportional to the product of the two charges. Newton’s
law only produces attractive forces, since there is only one kind of
gravitational mass. Coulomb’s law
produces both attractive and repulsive forces, since there are two kinds of
electrical charge.
