In the last question let us assume that the uniform electric field makes an angle `theta` with the vertical in downward direction. With the uniformly charged rod in vertical position the field is switched on. Mass of the rod, its length and charge per unit length is M, L and `lamda` respectively. (a) Find the strength of field (E) such that the rod can reach the horizontal position if `theta = 30^(@)` (b) Find the minimum strength of field (E) such that the rod can reach the horizontal position if `theta = 60^(@)` (c) However high the field might be, the rod cannot become horizontal if `theta lt theta_(0)` find `theta_(0)`
