Answer:
drift change = 4.5241 × 10^-7 C
Explanation:
Given data
potential difference = 3.10 nV
length= 2.09 cm
radius = 2.32 mm
to find out
charge drifts through a cross section in 3.05 ms
solution
we will apply here drift change formula that is
drift change = potential difference × π × radius² × time / resistance × length
put all the value and we get drift change
drift change = 3.10 × 10^-9 × π × (0.00232)² × 3.05× 10^(-3) / 1.69×10^(-8) × 0.0209
