you have to divide the mass by the volume then measure the ends then you found your answer
how do you find the mass of a sphere Volume x density => 4/3(pi)(r)3 x density
The formula for calculating the charge density of a sphere is Q / V, where is the charge density, Q is the total charge of the sphere, and V is the volume of the sphere.
To find the radius of the aluminum sphere, you need to know its density. Without density information, it's not possible to calculate the radius just from the mass given.
The surface charge density formula of a sphere is Q / 4r, where is the surface charge density, Q is the total charge on the sphere, and r is the radius of the sphere.
The charge density formula for a sphere is Q / V, where is the charge density, Q is the total charge, and V is the volume of the sphere.
Volume of anything = (its mass) divided by (its density) regardless of what shape it happens to be.
Density = mass / volume. You have the density of aluminum and the mass of the aluminum sphere. The volume of a sphere is 4/3*Pi*r^3. Therefore volume = 4/3*Pi*r^3 = mass / density. Solve for r, which is the radius of the sphere.
calculate the volume using the formula: Vsphere = (4/3)*pi*r^3 then calculate density by Density = Mass/Volume
The formula for calculating the surface charge density of a sphere is: Q / 4r, where represents the surface charge density, Q is the total charge on the sphere, and r is the radius of the sphere.
a gold sphere
To find the volume of the sphere, you need to know the density of the material the sphere is made of. With just the mass provided (75 grams), you cannot calculate the volume without this additional information.
Density is the mass per unit volume. e.g. kg/m3. But you've only given one of the quantities needed - we still need the volume of the sphere.
