The potential in a region of space due to a charge distribution is given by the expression v = ax2z + bxy − cz2 where a = −3.00 v/m3, b = 6.00 v/m2, and c = 9.00 v/m2. what is the electric field vector at the point (0, −8.00, −8.00) m? express your answer in vector form

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.
