The object is spherical and roughly 17.3 cm in diameter 4.030 x10% N/C at a distance of 39.5 cm from its surface. Furthermore, they claim that the electric strength is fairly constant at this distance from the surface. In the script, the scientists claim that such a charge is so enormous that the object must be extraterrestial! Caloulate the charge on the object according to the specifications listed in the script. (Enter only a positive value.) Number Choose one of the following suggestions you would offer the script writers The charge on the object is not unusual. You need a much larger E-field written in the soript. The charge on the object is not unusual. You need a much smaller E-field written in the script. The charge on the object is truly fantastic, lending O credence to the notion that the object is extraterrestial. Previous 9 Check Answer 0 Next

Explanation / Answer

E = k Q / r^2

r = (17.3/2) + (39.5) = 48.15 cm = 0.4815 m

E = k Q / r^2

(4.030 x 10^5) = (9 x 10^9) (Q) / (0.4815^2)

Q = 10.4 x 10^-6 C ....Ans

Ans: the charge on the object is not unusual. You need a much larger E-field written in the script,
