Can work done by a non - conservative force be positive ?

The work done by the conservative force in a cycle is

if work done by a conservative force is positive the select the correct option(s). (a) potential energy will decrease. (b) potential energy may increase or decrease. (c )kinetic energy will increase. (d) kinetic energy may increase or decrease.

Work done by the conservative force on a system is equal to :

Work done by the conservative force on a system is equal to :

If work is done on system by non-conservative force, then potential energy increases.

Is work done by a non conservative force always negative ? Comment.
