The pointer of an analog meter is connected to a
a. permanent magnet.
c. coil suspended by bearings.
b. electromagnet.
d. voltage to frequency converter circuit.

the correct answer is c coil suspended by bearings.

Explanation: this is so that whenever the coil detect a parameter to be measured say current voltage or resistance it energizes and the bearings moves accordingly to indicate the corresponding reading

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?

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
