A pollen grain has a maximum electric charge it can carry before the electric field it generates exceeds the dielectric limit for air of 3 × 10 6 N / C . 3×106 N/C. Estimate the magnitude of the maximum voltage V max Vmax at the surface of a pollen grain that is carrying its maximum electric charge, assuming V = 0 V=0 at infinity.

18 V

Explanation:

Let

r = Radius of pollen grain = (general value)

E = Electric field =

Electric field is given by

Voltage is given by

The maximum voltage is 18 V

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
