I was reading the following article regarding solution of wavefunction of hydrogen : http://skisickness.com/2009/11/22/ To solve the angular part they gave the substitution of y = \sin \theta and then assumed that Y is a polynomial i.e. Y(y) = \sum b_n x^n and then arrived at the...

I agree that the tangent to the electric field line points in the direction of the force. But then two field lines can have the same tangent at the point of intersection and the resultant will be in the direction of the tangent.

Why can't two field lines intersect? The answer that i have often heard is that if they were to intersect, then there would be two different directions for force. But then two field lines can interesct in such a way that their tangetes at the point of intersection point in the same direction. (...

v2 - u2 = 2as v = 0 u = 9.7 m/s a = -9.8 m/s/s -9.72 = 2*(-9.8)*s s = 9.72/(2 * 9.8 ) s = 4.8 m
