1.Convert the following vectors to cylindrical and spherical systems: F = ra, +yay+za, G = [ra, +ya, + za] 2.The acceleration of a particle is given bya = 2.4a,m/s2. The initial position of the particle is r = (0, 0, 0), while its initial velocity isv =-2a, + 5a,m/s. (a) Find the position of the particle at time t = 1. (b) Determine the velocity of the particle as a function of t 3.Prove that (1) V. (VA) = VV A+ AVV where V is a scalar field and A is a vector field, (2) Evaluate V (VA) whenA 2ray + 3yay-4zazand V = ryz. Let A = psinda, + pas. Evaluate , A dl given that (1) L is contour given fig 1.0 fig 1.0 4.A charge distribution in free space has p, = 2rnC/m for 0srs 10mand zero otherwise. Determine E at r= 2m andr 12m. 5.Ring placed along y2 + z2 = 4, x = 0 carries a uniform charge of 5 uC/m. (1) Find D at P(3,0, 0). (2) If two identical point charges Q are placed at(0,-3, 0)and (0,3,0) in ad- dition to the ring.find the value of Q such that D 0 at P.
