Question

In physics, by definition, a force is said to do work: Select one: O A. When effort is exerted to move one kilogram of mass a unit distance. O B. If, when acting, there is a displacement of the point of application in the direction of the force. O C. When effort is exerted to move one kilogram of mass by one metre. O D. If, when acting, there is a displacement of a mass equal to the mass multiplied by the displacement.

Answer 1

In ginem by = phyores pics the work done u Work alone = rod = Fd camo where, F = face e capplied on the object de displacement of lhe object angle between the face and displacement. Bo, in order to have work, the object should move on the direction of the applied #so, a force au pould to do wook, zb when acting , there is a displacement of the point of application in the direction of the foal, applied foce, as per the above gaven equation, i.e, opfron " B

Comment

Option B is the correct statement for work done by a force, the reason for the same is explained above.
