A bug zapper consists of two metal plates connected to a high-voltage power supply. The voltage between the plates is set to give an electric field slightly less than 1×10⁶ V/m . When a bug flies between the two plates, it increases the field enough to initiate a spark that incinerates the bug.
If a bug zapper has a 7000 V power supply, what is the approximate separation between the plates?
(a) 7×10⁻² cm
(b) 0.7 cm
(c) 7 cm
(d) 70 cm

(b) 0.7 cm

Explanation:

E = Electric field =

V = Voltage = 7000 V

d = Seperation between the plates

Electric field is given by

The approximate separation between the plates is 0.7 cm

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
