Some planetary scientists have suggested that the planet mars has an electric field somewhat similar to that of the earth, producing a net electric flux of 3.69×1016 n⋅m2/c into the planet's surface. part a: calculate the total electric charge on the planet. part b: calculate the magnitude of the electric field at the planet's surface (refer to the astronomical data inside the back cover).

Part a)

Part b)

Explanation:

Part a)

As we know that flux is defined as

here we have

now we have

Part b)

Also we know that the radius of the planet is given as

now the electric field is given as

here we have

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.)

the answer would be   dignified - apex
