4.1 Work Done by a constant Force
... A frictional force acts and does work on any surfaces that slide past each other. In each case, the frictional force transfers energy to surfaces, increasing their kinetic energy. The energy does not disappear. The increase in temperature occurs because of the motion of atoms at the surfaces. All su ...

E = kQ/r2 gives EI = 1.2 × 106 N/C to the right and EII = 0.4 × 106 N/C to the left The resultant field is therefore E = EI – EII = 8 × 105 N/C to the right e. From conservation of momentum mIvI = mIIvII and since th ...
