With t taken in seconds and I taken in amp, the variation of I follows the equation `t^(2) + I^(2) = 25`
What amount of Ag will be electrodeposited with this current flowing in the interval 0-5 second? (Ag=108)

A

22 mg

B

66 mg

C

77 mg

D

88 mg

Text Solution

Verified by Experts

The correct Answer is:
A
`i=(dq)/(dt), " " int dq=underset0overset5 idt, " " Q=underset0overset5int idt`
`Q=(pi(25))/4 C=(pixx25)/(4xx96500)F`
`therefore m=108/1 xx(pixx25)/(4xx96500) g =0.02197 g =21.97 g = 21.97 "mg" ~= 22` mg
