प्रश्न
Write the various types of potential energy. Explain the formulae.
उत्तर
(a) U = mgh
U – Gravitational potential energy
m – Mass of the object,
g – acceleration due to gravity
h – Height from the ground,
(b) u = `1/2"K" "x"^2`
u – Elastic potential energy
k – String constant;
x - displacement.
(c) U = `1/(4piepsilon_0) . (q_1q_2)/r`
U – electrostatic potential energy
ε0 = absolute permittivity
q1, q2 – electric charges
