under the electric field of a fixed point positive charge a point negative charge is moving in the XY plane and the path given by equation Y =x^2 . the coordinates of the fixed point positive charges (0,h) when the negative reaches the origin its velocity is Vm/s. Find out time taken by the negetive charge to go from A to B?

AB is a current carrying conductor in the plane of the paper as shown in the figure below. (i) What is the direction of the magnetic field produced by it at point ‘X’? Write the statement of the rule used to find the direction of field lines. (ii) If the polarity of the battery connected to the wire is reversed, how would the direction of the magnetic field be changed? (iii) Point ‘X’ is at a distance r1 and point ‘Y’ is at a distance r2 (r1
