given, convex mirror so focal length is positive so f=15cm by cartisan sign rule.
object u=-10cm due to cartisan rule
applying mirror formula
1/f = 1/V+1/u
1/15= 1/V - 1/10
1/15+1/10 = 1/V
1/6=1/V
V=6cm
where V is position of image
by magnification formula
m=-V/u = -hi/ho
=> V/u = hi/ho
=> 6/10 = hi/140. (1.4 m = 140cm)
=> hi = 84cm here hi is height of image. CHEERS DUDE
