Storing music digitally requires less storage room than analog records or tapes. Digital music is easier to copy and the copies are the same as the original. The quality of the signal does not degrade over long periods of time.
The magnitude of the electric field just outside the surface of the sphere is
given:
radius,r=0.01m
charge,Q=1.0×10-9
what is electric field?
Electric field is defined as the electric force per unit charge.It is surrounded by electrically charged particles and exerts force on all other charge particles.
using formula,
for just outside r=radius of sphere
Thus,the electric field just outside the surface of the sphere is
