T3 PS - Electrostatics

The diagram alongside represents a magnetic field pattern with a charge of

 $+6\times10^{-6}\ C$ .

Is the diagram correct? 

Yes or No?  

Sphere Y alongside carries a charge of    $+6\times10^{-6\ }C$ . If   $8\times10^{13}$  electrons are now transferred to sphere Y , calculate the electric field at a point 0,5 from the sphere. 

Choose the correct answer. 

•  $2,45\times10^{5\ }N\cdot C^{-1}$  Towards sphere

•  $2,5\times10^5N\cdot C^{-1}$  Away from sphere

Choose the correct definition for Coulombs law.

• The magnitude of the electrostatic force exerted by one point charge on another point charge is directly proportional to the product (of the magnitudes) of the charges and inversely proportional to the square of the distance between them

• The magnitude of the electrostatic force exerted by one point charge on another point charge is indirectly proportional to the product (of the magnitudes) of the charges and inversely proportional to the square of the distance between them
