Apoint charge of -3.00 μc is located in the center of a spherical cavity of radius 6.90 cm inside an insulating spherical charged solid. the charge density in the solid is 7.35 × 10−4 c/m3.part acalculate the magnitude of the electric field inside the solid at a distance of 9.20 cm from the center of the cavity. express your answer with the appropriate units. ee=

Electric field will be                        

Explanation:

We have given that a charge of is inside the cavity of sphere

Charge density of sphere

Radius of cavity = 6.90 cm = 0.069 m

We have to find the electric field at 9.20 cm = 0.092 m

So effective radius = 0.092 - 0.069 = 0.023 m

So effective volume

We know that charge = volume × charge density

So charge

So net charge enclosed by sphere

From Gauss law we know that

the answer is 46 mls because when you add the speed per second it increses the speed

dang that balls went far
