Let the length of copper wire be L and then
resistance r1=row ×L^2/v
new length =L+0.1%of L
=101L/100
now, new resistance r2. =row ×(101L/100)^2/v
=row×1.0201L^2/v
remaining resistance = r2-r1
0.0201L^2×row/v
increase percentage of resistance=(0.0201L^2×row/v)×100/(row×L^2/v)
now u can calculate the percentage
resistance r1=row ×L^2/v
new length =L+0.1%of L
=101L/100
now, new resistance r2. =row ×(101L/100)^2/v
=row×1.0201L^2/v
remaining resistance = r2-r1
0.0201L^2×row/v
increase percentage of resistance=(0.0201L^2×row/v)×100/(row×L^2/v)
now u can calculate the percentage
