Answer:

DEFINE OF CENTREL FORCE

In classical mechanics, a central force on an object is a force that is directed along the line joining the object and the origin:[a][1]

In classical mechanics, a central force on an object is a force that is directed along the line joining the object and the origin:[a][1]{\displaystyle {\vec {F}}=\mathbf {F} (\mathbf {r} )=F(\mathbf {r} ){\hat {\mathbf {r} }}}{\displaystyle {\vec {F}}=\mathbf {F} (\mathbf {r} )=F(\mathbf {r} ){\hat {\mathbf {r} }}}

In classical mechanics, a central force on an object is a force that is directed along the line joining the object and the origin:[a][1]{\displaystyle {\vec {F}}=\mathbf {F} (\mathbf {r} )=F(\mathbf {r} ){\hat {\mathbf {r} }}}{\displaystyle {\vec {F}}=\mathbf {F} (\mathbf {r} )=F(\mathbf {r} ){\hat {\mathbf {r} }}}where {\displaystyle \scriptstyle {\vec {\text{ F }}}} \scriptstyle \vec{ \text{ F } } is the force, F is a vector valued force function, F is a scalar valued force function, r is the position vector, ||r|| is its length, and {\displaystyle \scriptstyle {\hat {\mathbf {r} }}} \scriptstyle \hat{\mathbf{r}} = r/||r|| is the corresponding unit vector.

However, a central force is conservative if and only if it is spherically symmetric.
