Answer:

The charge on each plate of the capacitor is 19.38 \mu C

with one plate positive and one negative, i.e., \pm 19.38 \mu C

Solution:

According to the question:

Critical value of Electric field, E_{c} = 3.0\times 10^{6} V/m

Area of each plate of capacitor, A_{p} =73 cm^{2} = 73\times 10^{- 4} m^{2}

Now, the amount of charge on the capacitor's plates can be calculated as:

Capacitance, C  = \frac{epsilon_{o}\times Area}{Distance, D}        (1)

Also, Capacitance, C = \frac{charge, q}{Voltage, V}

And

Electric field, E = \frac{Voltage, V}{D}

So, from the above relations, we can write the eqn for charge, q as:

q = \epsilon_{o}\times E_{c}\times A_{p}

q = 8.85\times 10^{- 12}\times 3.0\times 10^{6}\times 73\times 10^{- 4}

q = 19.38 \mu C

Hello, how's your day going?

if humanity came together and made a base on the moon, it would be revolutionary. The point of a base on the moon would have multiple purposes. for example, some think that the moon contains valuable metals such as iron and titanium. a base would serve as a place for workers harvesting metals to rest. Obviously or not most of the iron harvesting would be done automatically by robots and such.

If such a base were constructed on the moon, it would be the begining of people living on other worlds and would be a great start for a base on Mars.

Hope it helped
