A negatively charged rod is brought near a neutral insulator. The insulator is attracted to the rod mainly because:

A point charge of `q` nC is at a distance `r` cm from a point in space.Find the magnitude of the electric field at that point in N/C.

At a point PP, the distances to two charges are `r1` cm (to q1q_1​) and `r2` cm (to q2q_2​).If q1=q_1=`q1_uC` μC and q2=q_2=`q2_uC_neg` μC (negative), find the electric potential V(P)V(P) in volts (V).Use V=k(q1r1+q2r2)V = k\left(\dfrac{q_1}{r_1} + \dfrac{q_2}{r_2}\right).

A solid conducting sphere is in electrostatic equilibrium with net charge +Q+Q. Which is true?

One’s professional career in the radiologic sciences begins with the attainment of a primary credential.  For those following this, continuing competency is demonstrated by achieving proof of continuing education (CE) through a process referred to as:

Professional certification of radiographers is:

Accredited programs in radiologic technology are recognized by the Joint Review Committee on Education in Radiologic Technology (JRCERT).  Programs seeking this programmatic recognition necessarily must comply with the JRCERT
