Question

hey guys answer it faster

Answer 1

1/v+1/u=1/f
1/v+1/-10=1/15
1/v=1/15+1/10
Solve it u will get the ans.

Answer 2

Given Convex Mirror
 u = -10
 f = 15
 v = ?

By mirror formula

1/v + 1/u = 1/f
1/v +(1/-10 ) = 1/15
1/v = 1/15 - (1/-10)
1/v = 1/15 + 1/10
1/v = (2+3)/30
1/v = 5/30 = 1/6  thus 

v = 6cm

THus position of image is 6cm
Nature of image will be Dimnished , virtua and erect due to Convex Mirror.
