question mark

a galavano meter having resistance of 50 ohm gives full scale deflection for a current of 0.05 A the length in the meter of a resistance wire of area of croos section 0.00297 that can be used to convert the galavanometer in to ammeter which can read maximum 5A current is(specific resistance of wire 5*10^-7)

For ammeter setup formed using galvanometer
(i - ig) Rs  =  (ig) ×(Rg)
(5 - 0.05)Rs = 0.05×50
So  Rs = 0.50 =( rho) L/A
 
(5*10^-7)(L)/0.00297 = 0.50
So L = 2.97*10^-11
Here
Rs = shunt resistor
Rg = resistance of galvanometer
ig = current in galvanometer 
i = total current given

You must provide units of all measurements. 
IT is not a correct question. So please provide units also.

Two parallel beams of light P and Q are incident normally on a prism and the transmitted rays are brought to focus with the help of a convergent lens as shown. If the intensities of the upper and lower beams immediately after transmission from face AC are 4I abd I, respectively, find the resultant intensity at the focus.
