According to the script, when scientists place a test Instrument near the object

Question

According to the script, when scientists place a test Instrument near the object, It registers an electric field magnitude 3 030 x 10^5 N/C at a distance of 33 5 cm from Its surface Furthermore, they claim that the electric field strength is fairly constant at this distance from the surface. In the script, the scientiste claim that such a charge is so enormous that the object must be extraterrestial! Calculate the charge on the object according to the specifications listed in the script. (Enter only a positive value.) Choose one of the following suggestions you would offer the script writers

Explanation / Answer

Here,

Total distance = 33.5 + (21.3 / 2) = 44.15 cm = 0.4415 m

E = kQ/d^2 ; Q=Ed^2/k

Q = (3.030 * 10^5)*(0.4415^2)/(8.99*10^9) = 6.5697x10^-6 C

So the charge is not unsual and we need a higher Electric Field
