mirror formula :- (1/v) + (1/u) = (1/f)  ..................(1)
 
v is mirror-to-image distance, u is mirror-to-object distance and f is focal length
 
as per sign convention, u = -10 and f = +10 (convex mirror)
 
By substituting values in eqn.(1),  (1/v) = (1/10) + (1/10) = 1/5    or  v = 5 cm
 
since v is +ve, virtual image will be formed at 5 cm behind the convex mirror
