Explanation:

F=10N,S=2m,θ=600

So, Work=F×Scosθ=10×2cos600

=10×2×21=10J

Answer:

pls mark as brainliest

Explanation:

(a) In physics, work done is actually always with the aspect of an external agent which is known to produce a force on some other entity. The work is stated as zero when there is no displacement of any given object along a line of force.

(b) F = 10N, S = 2m, θ = 60⁰

So, Work=F×Scosθ = 10×2cos60⁰

=10×2×1/2

=10J
