A) two 0.500 g raindrops in a thunderhead are 1.00 cm apart when they each acquire 1.00 mc charges. find their acceleration. (b) what is unreasonable about this result? (c) which premise or assumption is responsible?

Explanation:

Given that,

Mass of the raindrops,

Charges,

Distance between raindrops, d = 1 cm = 0.01 m

(a) The force due to motion of raindrop is balanced by the electric force between charges. It is given by :

a is the acceleration of the raindrop

(b) It is clear that the acceleration is too large. It can break apart the rain drop.

(c) If the charge is of the factor of , the charge would be more reasonable.            

Hence, this is the required solution.  

d

explanation:

v=uf/(u-f)
