The electric field at the surface of a charged, solid, copper sphere with radius 0.230 m is 4100 N/C , directed toward the center of the sphere. What is the potential at the center of the sphere, if we take the potential to be zero infinitely far from the sphere?

Given Information:  

Electric field = E = 4100 N/C

Radius of sphere = r = 0.230 m

Required Information:  

Potential = V = ?

Potential = 9.43×10² Volts

Explanation:

The relation between electric field and potential is given by

V = Er

Where E is the electric field at the surface of charged sphere and r is the radius of sphere

V = 4100*0.230

V = 9.43×10² N.m/C

1 Volt is equal to 1 N.m/C

V = 9.43×10² Volts

Therefore, the potential at the center of the sphere is 9.43×10² Volts.

the correct answer is b

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
