In a region magnetic field along x axis changes with time according to the given graph. If time period, pitch and radius of helix path are T_(0),P_(0) and R respectively then which of the following is incorrect if the paticle is projected at an angle theta_(0) with the positive x-axis in x-y plane from origin:

Answer»

At `t=T_(0)/2`,co-ordinates of charge are `(P_(0)/2,0,-2R_(0))`.
At `t=3T_(0)/2`,co-ordinates of charge are `(P_(0)/2,0,-2R_(0))`.
TWO EXTREMES from `x`-axis are at a DISTANCE `2R_(0)` from each other.
Two extremes from `x`-axis are at a distance `4R_(0)` from each other.
