Two identical charges +Q are kept fixed some distance apart. A small particles P with charge q is placed midway between them . If P is given a small displacement Δ ,it will undergo simple harmonic motion if (i) q is positive and Δ is along the line joining the charges (ii) q is positive and Δ is perpendicular to the line joining the charges (iii) q is negative and Δ is perpendicular to the line joining the charges (iv) q is positive and Δ is along the line joining the charges

Two small balls having equal positive charges Q( coulomb) on each are suspended by two insulating strings of equal length L(metre) from a hook fixed to a stand. The whole set up is taken in a satellite into space where there is no gravity (state of weightlessness). Then angle between the two strings is.
