1 The position vector r. with respect to a given origin o. of a charged particle of mass m and charge e attimet is given by: Et + a sin())i + a cos(ost)+etke where EB, a and w are constants. a) Determine the corresponding velocity and acceleration [3 Marks] b) For the case of when B Bk, determine the equation of motion [3 Marks) 2. Given that the electric field at a point having position vector, due to a charge e at R, is e(r - R)/Ir-R]. Find the electric field E at the point P(2. 1. 1) given that there is a charge eat each of the points (1.0.0), (0.1.0) and (0.0.1). 18 Marks] 3 According to the inverse square law, the force on a particle of mass m, at the point P, due to a particle of mass my at the point P, is given by: Y = P₂ P2 Particles of mass 3m, 3m, m are fixed at points All. 0. 1), B(O. I. 2) and C12. 1. 2) respectively. Determine the force on the particle at A due to the presence of B and C. [6 Marks! 704 mm2 f wherera
