A particle moving in the xy plane undergoes a displacement `vec(S) =( 2.0 hat(i) + 3.0hat(J) )m` while a constant
force `vec(F) = (5.0 hat(1) + 2.0 hat(j) ) ` N acts on the particle.
(a) Calculate the magnitude of the displacement and that of the force.
(b) Calculate the work done by the force

A

17 joule

B

18 joule

C

16 joule

D

15 joule

Text Solution
