The marble's volume is equal to 1.2 
Density= mass/volume
Mass= 3.05 Grams
Volume= 1.2 cm^3
3.05/1.2= 2.92 <span>g/mL</span>

Answer:
The correct option is D
Explanation:
From the question we are told that
The speed of the first charge is
This is because it is at rest
The speed of the second charge is
Generally the force exerted by a magnetic field on a charge is mathematically represented as
Now looking at this above equation we can see that can only be maximum at
and this only obtained when the direction of the charge (i.e its velocity ) is perpendicular to the direction of the magnetic field
so the correct option for this question is D
