 Hi guys, so in the same series question number 12 an object is placed at a distance of 10 centimeter from a convex mirror Again convex mirror focal length is positive Object distance under any circumstances are negative image distance in all scenarios for a convex mirror are positive Yeah, an object is placed at a distance of 10 centimeter From a convex mirror clear then comes Focal length of this concave X mirror is 15 centimeter find the position and nature of image so 1 upon F equal to 1 upon V Actually plus 1 by you but because of the negative sign of the you it will become negative Goes this side so 1 upon V equal to 1 upon 15 plus 1 upon 10 30 be the LCM 2 here 3 here 5 1 upon 6
