Use the de Broglie wavelength formula (λ = h/p) to find the wavelength associated with a golf ball of mass 60 grams and speed 30 m/s. Does is seem likely that the wave properties of this golf ball could be easily detected?

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

6 times more

more than, less

less than, more

it is a negative acceleration

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
