Explanation:
power of old pair of corrective glasses is given as
now we have
now we know that for normal vision the maximum distance of vision is for infinite distance
so by lens formula we have
so his far point according to this pair of glass is 200 cm
Explanation:
It is known that relation between pressure and density is as follows.
P =
where, P = pressure
= density
g = acceleration due to gravity
h = height
Putting the given values into the above formula as follows.
P =
=
= 110495000 Pa
Now, relation between pressure and force is as follows.
P =
or, F = PA
F =
=
Thus, we can conclude that a force of can be experienced at such depth.
