3/2 I think as well

3/2 I think as well
but wasn’t the work on one calculated using 1/2d and the work on the other using 3/2d? because all the other factors are the same wouldn’t that make it 3x? what’ve I done wrong?

Distance 3 times
E field strength 1/2

#### black.mamba

Because voltage constant and distance between plates is doubled so e field halved

E for the second scenario was different as well! Since E = V/2d

ahhhh shit I’m such a dipshit - I made that error in the last question too then. root 3 isn’t the answer for the last one

I got mass too. What about the rocket thruster one? I guessed that

Rocket thruster it was accelerating upwards parabolically

Also why mass?
