Answer:
v=66.67cm , m=0.67 and the image will be virtual, erect and small in size with respect to the object.
Given in, f=200cm, u=-100cm so, we can use mirror formula 1/f=1/v+1/u. We get v=66.67 cm , because v is +ve ,we can say image will be virtual and a convex mirror always gives a erect and small image .Now we can find magnification by m=-v/u that gives m=0.67
