A small sphere with mass 5.00.*10-7kg and charge + 3.00μC is released from rest a distance of 0.600 m above a large horizontal insulating sheet of charge that has uniform surface charge density σ=+8.00pC/m2. Using energy methods, calculate the speed of the sphere when it is 0.100 m above the sheet of charge?

A small sphere with mass 5.00.*10-7kg and charge + 3.00μC is released from rest a distance of 0.600 m above a large horizontal insulating sheet of charge that has uniform surface charge density σ=+8.00pC/m2. Using energy methods, calculate the speed of the sphere when it is 0.100 m above the sheet of charge?

Given:

m = 5.00x10^-7 kg

q = 3.00 μC

To determine the velocity, use this formula

v = √ (2qΔx/m)

Now, solve for the velocity, substitute the given values to the equation

v = √ (2 (3.00μC * 0.600m/5.00x10^-7 kg)

Solve for V and this is the velocity of your sphere in condition 1.
