Charge is placed on two conducting spheres that are very far apart and connected by a long thin wire. The radius of the smaller sphere is 5 cm and that of the larger sphere is 12 cm. The electric field at the surface of the larger sphere is 660 kV/m. Find the surface charge density on each sphere.

surface charge density on each sphere is C

Explanation:

given data

radius of smaller sphere = 5 cm

radius of  larger sphere is 12 cm

electric field at surface of larger sphere = 660 kV/m = 660 × 1000 v/m

solution

we apply here electric field formula that is express as

E =    .................1

put here value

660000 =  

Q1 = 1056 ×

and

here field inside a conductor is zero so that electric potential ( V ) is constant

  ..................2

so Q2 will be

Q2 =    

Q2 =    C

a. is the answer because they are not shared

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
