Answer:
Im not so sure about this bit I guess it's a comma
The electric field at a distance r from the charged particle is given by :
k is electrostatic constant
if r = 2 m, electric field is given by :
If r = 1 m, electric field is given by :
Dividing equation (1) and (2) we get :
So, at a point 1 m from the particle, the electric field is 4 times of the electric field at a point 2 m.
Answer to first Question is yes. Seeing as though it started cause of a series of weaknesses in the economy.
And There was no single cause for the stock market crash.
A soaring, overheated economy that was destined to one day fall likely played a large role. Equally relevant issues, such as overpriced shares, public panic, rising bank loans, an agriculture crisis, higher interest rates and a cynical press added to the disarray.
