The mass of an electron is `9.11 x 10^-31` kg, that of a proton is `1.67 x 10^-27` kg. Find the ratio `F_e// F_g` of the electric force and the gravitational force exerted by the proton on the electron.- |
Answer» Correct Answer - A::B::C `F_e=1/(4piepsilon_0)(q_1q_2)/r^2` `and F_g=G(m_1m_2)/r^2` `:. F_e/F_g=((1//4piepsilon_0)q_1q_2)/(Gm_1m_2)` `=((9xx10^+9)(1.6xx0^-19)^2)/((6.67xx10^-11)(9.11xx10^-31)(1.67xx10^-27))` `=2.27xx10^39` |
