Acertain microscope is provided with objectives that have foal lengths of 16 mm, 4 mm, and 1.9 mm and with eyepieces that have angular magnifications of 5x and 10x. each objective forms an image 120 mm beyond its second foal point. determine a) the largest overall angular magnification obtainable; b) the least overall angular magnification obtainable.

the first, second, and fifth options

object 2 because all the other ones are wrong

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

the ima (higher than 1m) will be greater than the ima with the height of 1m.
