Jason knows that the equation to calculate the period of a simple pendium t=2π√l/8, where t is the period, l is the length of the rod and g is the acceleration due to gravity. he who knows that the frequency (f) of the pendulum is the reciprocal of period. how can he express l in terms of g and f?

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:

formula.

example:

given values:

mass = 0.3 kg.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
