Charged small sphere in a uniform electric field?

Question

A small sphere with a charge of -6.0 10-7 C is placed in a uniform electric field of magnitude 1.2 106 N/C pointing to the west. What is the magnitude and direction of the force on the sphere due to the electric field?

Answer 1

Force = electric field * charge = -6 x10^-7 *1.2 x 10^6 N

= -0.72 N the force points to the east hence the negative sign.

Answer 2

WebAssign won't settle for a denominator in parentheses. WebAssign will mark this incorrect inspite of the actuality that that is suited: (a*b*c)/(x*y*z) quite, enter this into WebAssign: a*b*c/x/y/z attempt E=(((r^3)-(R^3))*d)/3/ez/r^2
