Answer 2

first use the formula,

  1/v-1/u=1/f=2/R -------convex mirror formula

put the values as u = -20 , R= 30  

by this you can find v

now we are given object's height 5 cm

 m=HEIGHT OF OBJECT'S IMAGE/HEIGHT IF OBJECT = V/U

 5/h=v/20 -----in this equation you can find h because you know v.

and find height of image and its nature--- (erect) (virtual)
