Question

Ted wants to hang a wall clock on the wall by using a string. If the mass of the wall clock is 0.250 kilograms, what should be the tension of the string so that it can sustain the weight of the wall clock?

Answer 1

T=mg+ma the formula for tension when object not moving.
T=tension
m=mass
g=acceleration of gravity
a=acceleration

a=0 since its not moving.

Answer 2

The tension should be 0.25
