#70# joules.

Explanation:

Work done #(W)# by a force #(F)# is equal to the dot product of the force and displacement and the cosine of the angle #(theta)# between the two #(S)#.

Hence,

#W=FcdotScos(theta)#

Here, the angle #theta# is #0°#.

So, #cos0°=1#

#:.W=20xx3.5J#

#:.W=70J#. (Answer).

Hope it Helps:)
