q = [(ΔϕΔt)1 / R]Δt
 
q = [μ0nNπr^2Δi/Δt]1/RΔt
 
q = [4×10^−7×2×10^4×100×π×(10^−2)^2×(40.05)] 1 /10π^2×0.05
 
q = [ 2512  x 10-7+4 -4 x 4 / 0.05] 1/10 x 3.14 x 3.14 x 0.05
 
q = [ 2.5 x 10^-4 x 4/ 0.05 ] x 1/ 98.59 x 0.05
 
q = 32 μC
 
Thus the total charge flowing through the coil during this time is q = 32 μC
 
 
Hope it helps
