A block weighing 20 N is lifted 6 m vertically upward. the potential energy stored in it is:
A block weighing 20 N is lifted 6 m vertically upward. the potential energy stored in it is:
20 N وزنی بلاک کو 6 میٹر عمودی طور پر اوپر کی طرف اٹھایا جاتا ہے۔ اس میں ذخیرہ شدہ ممکنہ توانائی یہ ہے
Explanation
Weight(mg) of a block = 20N
Height (h) = 6m
Now, potential energy(PE) = mgh
=20 × 6
= 120Joules
The potential energy stored in it is 120 joules.
