It should be in Coulombs.

Homework Statement An alpha particle approaches at high speeds a gold nucleus with a charge of 79e. What is the electric force acting on the alpha particle when it is 2.0e-17 m from the gold nucleus? Homework Equations FE=k(q1q2)/d2 The Attempt at a Solution FE=k(q1q2)/d2...

This is what I initially thought it would be, but this is all that my professor gave me. I will ask him. Thank you.

Homework Statement Express a polynomial in terms of the basis vectors. {x2 + x, x + 1, 2} Homework Equations 3. The Attempt at a Solution [/B] I think the answer is: (x2+x)^2 + (x + 1) + 2 = 0 simplified to become: x4 + 2x3 + x2 + x + 3 = 0
