Answer:
C. zero for both
Explanation:
In case of solid metal sphere , when it is given any charge , all the charges are transferred on the surface and within surface no charge exists . In case of hollow metal sphere , all charges reside on surface . In this way , in both solid and hollow sphere , all charge reside on the surface and no charge resides inside it . Hence due to absence of any charge inside , there is no electric field inside the sphere in both the cases .
Hence in both the case electric field is zero .
option C is correct .

Pressure = force / area
= (59.5 x 9.81) / (1.6x10^-3)^2
my calculator is too far from me but ive pretty much done it for you :)
Answer: 3
Explanation:
Lithium always has 3 protons bc it’s atomic number is 3 which is determined by its amount of protons.
