(L+uncertainty -Lo)x7.14/100 is the max
(L-uncertainty-Lo)x 7.14/100 is the min right ?

A minus sign aswell?
cuz gradient had to be negative and p= -gradient and well my value was also -ive

And my e value was -1.53x10^-19 and the percentage diff was 4.48 so I wrote its accurate!

I guess you messed up with signs cuz e is -1.60x10^-19 not 1.60x10^-19

So readings on voltmeter when switch is connected to terminal A and B?
What graph did you guys say to plot to find Cx for the capacitor question?
