You are asked to give the answer in <span>g/cm3. So without knowing any single formulae you can just divide grams by cm3. 
</span>

 = 4.5 g/cm3
 
        
        
        
Explanation:
Here are some of the ways that energy can change (transform) from one type to another:
The Sun transforms nuclear energy into heat and light energy.
Our bodies convert chemical energy in our food into mechanical energy for us to move.
An electric fan transforms electrical energy into kinetic energy.
 
        
             
        
        
        
The magnitude of the electric force on the charge is 5 N.
<h3>Magnitude of force on the charge</h3>
The magnitude of force on the charge is calculated as follows;
F = Eq
where;
- E is electric field
- q is magnitude of the charge
F = 100 N/C  x 0.05 C
F = 5 N
Thus, the magnitude of the electric force on the charge is 5 N.
