A particle of mass `m_(2)` carrying a charge `Q_(2)` is fixed on the surface of the earth .Another particle of mass `m_(1)` and charge `Q_(1)` is positioned right above the first one at an altitude `h( ltlt R)`.R is radius of earth ,the charge `Q_(1)` and `Q_(2)` are of same sign ,then At what altitude of `h_(3)` will object `m_(1)` be in equilibrium and what will be the nature of objects in motion if it is disturbed slightly from equilibriumA. `h_(3)=sqrt((Q_(1)Q_(2))/(4piepsilon_(0)m_(1)g))` periodic non oscillatoryB. `h_(3)=sqrt((Q_(1)Q_(2))/(2piepsilon_(0)m_(1)g))`,periodic and oscillatory.C. `h_(3)=sqrt((Q_(1)Q_(2))/(4piepsilon_(0)m_(1)g))`,periodic and oscillatory.D. `h_(3)=sqrt((Q_(1)Q_(2))/(4piepsilon_(0)m_(1)g))` non -periodic and non. |

Answer» Correct Answer - C `(1)/(4piepsilon_(0))(q_(1)q_(2))/(h_(3)^(2))=mg h_(3)=sqrt(q_(1)q_(2))/(4piepsilon_(0)mg)` |
