Answer:
We know that work done in any system is stored in form of negative of potential energy, so
>> W= -ΔU ...........1
>> ΔU= q(ΔV)
>> ΔU=q(V[final]-V[initial])
>> ΔU =2{v-(-10)} ...............2
from (1) & (2) we have
200 = -[2{v-(-10)}]
-100=v+10
v=-90 (V)
Potential at another place is -90 volts
I HOPE IT HELPS.
