Hello please help i’ll give brainliest

  concave means having an outline or surface that curves inward like the interior of a circle or sphere. so the mirror curves inward.

Special care would be an answer

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
