The closest distance a book can be read from a pair of reading eyeglasses (power = 1.55 dp) is 26.0 cm. what is the near distance? (assume a distance between the eyeglasses and the eyes to be 3.00 cm)

The image distance is 20.0 cm.

Explanation:

Given that,

Power = 1.55 dp

Distance between book to eye = 26.0+3.00=29.0 cm

We need to calculate the focal length

Using formula of focal length

Put the value into the formula

We need to calculate the image distance

Using lens formula

Put the value into the formula

Hence, The image distance is 20.0 cm.

we need to know the time interval during which the force acts. impulse of force = momentum change
