Figure shows three arrangements of an electrons e and two protons p(where Dgtd) (a) Rank the arrangement according to the magnitude of the net electrostatic force on the electron due to the protons placing the largest first. (b) In situation (c), is the angle between the net force on the electrons and the line labeled horiontal less than or more than 45^(@)? |
Answer» SOLUTION :   (a) It is CLEAR from the diagram that `F_(a)gtF_(c)gtF_(b)` (b) SINCE `F_(1)gtF_(2), tan theta =F_(1)/F_(2)` or `thetagt45^(@)`. |
