solution:
here,
mass(m)=10 kg
acceleration due to gravity(g)=50
height(h)=10
we know,
potential energy(p.e)=m*g*h
=10*50*10
=5000
the potential energy is 5000.

The image distance is 33.3 cm while the image height is 14.2 cm.
<h3>What is a converging lens?</h3>
A converging lens will always have a positive focal length hence, we have to find the object distance as follows;
1/f = 1/v + 1/u
1/12 = 1/v + 1/20
1/v = 1/12 - 1/20
1/v = 0.08 - 0.05
v =33.3 cm
Now;
Magnification = 33.3 cm/20.0 cm =1.67
M = Image height/Object height
1.67 = Image height/8.50 cm
Image height = 1.67 * 8.50 cm
Image height = 14.2 cm

My worldview is someone who doesn't exist. Someone who isn't real but i want them to BE real. It's not possible to have someone who is alike you. Who is there for yo when you need them
