Two objects have equal negative charge and repel each other with a force Fwhen separated by a distance x. Suppose the object on the left gets 4x its original charge,
the charge on the right is left alone, and the distance is between them is changed to
x. The force between the two objects is now

insects!

explanation:

80cm/s.

24cm/s.

53.3cm/s.

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
