Question

The potential energy function of a particle in the x-y plane is given by U = k(x + y), where 'k' is a
constant. The work done by the conservative force in moving a particle from (1, 1) to (2, 3) is
(A) - 3k
(C)k
(D) none of these
B1 + 3k​

Answer 1

Answer:

hєчα mαtє (^.^)

Explanation:

wσrk dσnє вч

conservative force = conservative force

=−△U

=U i −Uf

=[k(1+1)]−[k(2+3)]

=−3k
