What is the difference between a sell by date and use by date?

Sell by" is used by manufacturers to ensure proper turnover throughout the journey of the food product. This helps the food retain a long shelf life even after purchase. "Use by" marks the last date recommended for the use of the product.

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
