Hi,

begin mathsize 12px style Given space straight u space equals space minus 5 space cm space and space straight f space equals space 10 space cm
Using space the space mirror space formula space 1 over straight v equals 1 over straight f minus 1 over straight u
1 over straight v equals 1 over 10 minus fraction numerator 1 over denominator left parenthesis negative 5 right parenthesis end fraction equals 3 over 10
straight v space equals space 3.33 space cm
Thus comma space image space formed space is space virtual space in space nature.
end style
