Q.1 The force of attraction between the two particles is given by f = k(r2 ri) Vo where k is a constant, v, is a constant velocity, and r = |r2 - ri. Is the system conservative? Q.2 Examine whether the following forces are conservative or not, and, if so, determine the potential energy V. Fle) (r, y, z) = a (2.ayz, + az, + ay.), F (x, y, z) = B (ye-" + ze"e, + xy:), (B) where r2 = x+ y? + z2 and the constants a, B, and y.
