In this question, we have been given that potential v is equal to 100v, then 50v, then 25v and the charge is given as 8nc which is 8 times 10 raised to the power minus 9 c.
00:27
Then for each potential, we need to find the location and then between their relationship.
00:34
So here we can write that electric potential at any location r is given by v equal to k times q divided by r.
00:49
Since we need to find the value of this r, so location r can be written as k times q divided by potential v.
00:57
So first we have 100v of potential.
01:00
So let us consider this is case 1 and this r will be equal to the value of k is 9 times 10 raised to the power 9 and this q is 8 times 10 raised to the power minus 9 and this potential is 100.
01:18
Now since we are taking all the units in si unit, so this r will be in meter.
01:23
So on solving this, we will get r is equal to 0 .72 meter.
01:30
Then for second case, we have potential 50v...
