m= +3 = -v/u

=) v= 30 cm

1/f=1/v+1/u

=)1/f=u+v/uv

=)1/f= -10+30/-300

=20/-300

=)f= -15cm

R=2f= -30cm.

HOPE IT HELPED..

m = 3

therefore v= 30 cm

1/f = 1/v +1/u

= 1/30-1/10

On solving we get f = -15cm

But we need to find the value of R

hence we have the relation

R=2f

= 2 x -15

= -30cm

Therefore the radius of curvature of the concave mirror is -30 cm

HOPE U LIKED THE ANSWER :D
