1.	2 n force is applied to an object and it makes displacement 5 m in the direction perpendicular to force. Calculate the work done by the force.
Answer» rong>Topic :- Work energy and Power $\maltese\:\underline{\sf AnsWer :} \: \maltese$ Force Applied to an object (F) = 2 N DISPLACEMENT of the body (s) = 5 m θ = 90° [∵ Displacement is done in the direction PERPENDICULAR to the Force] We need to find the work done by the body. To calculate work done by the body we will use the GIVEN below formula : $\longrightarrow\:\sf Work \: Done = Fs \cos (\theta) \\$ Now, simply add the known values from the Question in the above given formula : $\longrightarrow\:\sf Work \: Done = 2 \times 5 \cos (90^{ \circ} ) \\$ $\longrightarrow\:\sf Work \: Done = 10 \cos (90^{ \circ} ) \\$ $\qquad \qquad\tiny \dag \: \underline{\sf \cos \: (90^{ \circ}) = 0}$ $\longrightarrow\:\sf Work \: Done = 10 \times 0 \\$ $\longrightarrow\: \underline{ \boxed{\sf Work \: Done = 0 \: J}}\\$ HENCE,the work done by the body is 0 J.
