Two charged particles attract each other with a force of magnitude F. If the distance between the charges is made 2.2 times as large and the charge on one of the particles is made 2.2 times as big, what is the ratio of the new F to the old one?

a, c, d, e are all applying about success strategies.

false

explanation:

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
