Answer:
Maximum distance of image from mirror is equal to focal length of the mirror
Explanation:
As we know by the equation of mirror we have
here we know for convex mirror
object position is always negative as it will be placed behind the mirror always
while the focal length of the convex mirror is always taken positive
So here we have
so here maximum value of image distance is equal to focal length of the mirror
Answer:
Magnitude of the force is
direction of the force is given as
West of South
Explanation:
As we know that force is a vector quantity and in order to find the resultant of two or more forces we need to add them vectorialy
So here we have
here we know that first force is of magnitude 2 N towards east
second force is also of 2.0 N due North
now from above equation
so magnitude of the force is given as
direction of the force is given as
West of South
