Question

work done in moving 5C charge across the ends of a conductor is 100
J if the potential at the one end of the conductor is 10V, find the
potential at the other end of this conductor

Dear Student,Given,W=100,Q=5C,V1=10VV1 is the potential at one end and V2 is the potential at the opposite end
We know,W=QV2-V1⇒V2-V1=WQAs W and Q are positive, the quantity,V2-V1 is also positive 
 So we takeV1=10V ⇒V2=WQ+V1=1005+10=20+10=30VRegards
