A5] A point particle moves with uniform angular velocity on a circular path centred on the origin, and is acted on by the field: r F(r) = -K- dr b dt in which K and b are positive constants, r is the position vector of the particle (with magnitude r) and t is a parameter. Using the standard parameterisation, x = a cost, y = a sint, (0 ≤ t ≤ 2π), find an expression for the field in terms of t and determine the work done during a single circuit of the particle. Hence state a condition for F(r) to be conservative.
