A force F of strength 20 N acts on an object of mass 3 kg as it moves a distance of 4 m. If F is perpendicular to the 4 m displacement, the work it does is equal to(A) oJ(B) 60 $\mathrm{J}$(C) 80 $\mathrm{J}$(D) 600 $\mathrm{J}$

So in order to think about this problem, we need to figure out the Adam and said we have been given. So we know that there's a force off funny Newton and it is smoothing an object that has a mass and off three kilograms. And we know that so far the after husband displaced So it has a displacement stay off four meters and since pose force and displacement are vouchers and we need to figure out the direction off the vouchers and we know we say that displacement is going forward, then the forces perpendicular to the disc movement and divide the direction in Seda. We'll see that the force has a direction off 90 degrees, since it's perfect decorative displacement. And then finally we come to the work, just the unknown the same. No need to solving this problem and to help yourself the work. We need to find an equation that we can utilize the elements we have so far and plug it into the equation. So the best thing that applies here would be this one work because to Forrest Times displacement 10 times, coz I didn't say that so and if we plan and say that First, which is 90 degrees. Who realized that co sign say that Coz I 90 degrees because 20 So in the end, we can see that when forces for been dicker to the div action that the after this morning the work that is done by the four slipping zero Joe's and that is the ends of the problem.
