What is the volume of a 100g object with a density of 50g/cm3? A. 5,000cm3
B. 2cm3
C. 0.5cm3
D. 2g

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

From the question we have

We have the final answer as

Hope this helps you

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
