Answer» Explanation: Given :- Force (F) = 10 N The HORIZONTAL force (Fx) = Fcos30° Fx = 10(√3/2) = 5 × 1.73 = 8.65 N Displacement (s) = 1 m ____________________________ To find :- WORK done (W) = ?____________________________ Solution :- We have, Work done (W) = Force × displacement => W = Fx × s => W = 8.65 × 1 => W = 8.65 J _____________________________ The work done is 8.65 J _______________________[ANSWER ] |
