Respuesta :

19-10-2020

Explanation:

from E = mc^2 and de Broglie wavelength=h/mc

combine the eqns with respect to m(considering the body is moving with the speed of light(c))

then

E= hc/de Broglie wavelength

since, c= 3× 10^ 8

h= 6.626 × 10^ -34 and E is given, substitute the values.

sorry I don't have my calculator.
