When two bodies `A` and `B` interact with each other, A exerts a force of `10N` on `B`, towards east. What is the force exerted by `B` on `A`?

Explanation

Here, force exerted by A on B `= F_(AB)=10N` (towards east)
force exerted by B on A ` =F_(BA)=?`
As `F_(BA)= -F_(AB), F_(BA)= -10N`,i.e., B exerts `10N` force on A towards west.
