In a certain two-dimensional field of force the potential energy of a particle has the form U = ax^2+by^2, where a and b are positive constants whose magnitudes are different. Find out: (a) whether this field is central; (b) what is the shape of the equipotential surfaces and also of the surfaces for which the magnitude of the vector of force F = const. |
