How much work is done when a book weighing 2.0 newtons is carried at constant velocity from one classroom to another classroom 26 meters away? 0.0 j 2.0 j 13 j 52 j it is not 52

Answer : The correct options is, 0.0 J

Solution : Given,

Applied Force = 2 N

Displacement = 26 m

Formula used :

where,

W = work done

F = applied force

d = displacement

At constant velocity, the acceleration will be zero and force acting of an object will also be zero. So, the work done is zero.

Therefore, the work done is, 0.0 J

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
