Kindly explain this Electric Charge and Fields •prudence force Of their 10 • 1.67 to • Solution between electron a proton "t a distance i he negative Sign indicates the force is attraetlve. The corvesponding gravitational force (always attractive) is: where m and me are the masseb or a proton and an electron respect i 2.4 4re„Gm m On similar 'Ines. the ratio .01 the magnitudes Of electric force to the gravitational force between two protons at a distance r apart IS : FG 4'teoGrn„rnv However. ii may be mentioned here that the signs of the two forces arc different. For two protons. the gravitational force is attractive in nature and the Coulomb force is repulsive . The actual values Of these lorecs between two orotons inside a nucleus (distance between two protons is — 10' m inside a nucleus) are — 230 N whereas Fc i .9 N. The (dime"sionless) ratfo of the two forces shows that electrical forces are enolTnously stronger than the gravitational forces. (b' •me electric force F cxcrtcd by a proton on an electron is same in magniludc• to Chc fortc exerted bv an electron on a proton: however the masses of an electron and a proton are different. Thus. the magnitude of force is 'Fl = 8.98/ x 10" Nm'/C2x (16 / (10-10m)2 -2.3 X Using Newton's second law of motion. F mas the acceleration that an electron will undergo is a = 23xlO*N / 9.11 2.5 x 1022m/s2 Comparing this with the value of acceleration due to gravity, we can conclude that the effect 01 gravitational field is negligible on the motion ot electron and it undergoes very large accelerations under the action 01 Coulomb force due to a proton. The value for acceleration of the proton is m o Cam
