Without a blush!

Except for the 10V part.  (Which I missed on the first post)

You have to use a capacitor that is at least 2x the operating voltage,
and is also greater than any peak voltages that could occur in the
boundary cases, such as the power line being at the scope's rated
maximum power line voltage.
