Question

The deBroglie wavelength associated with a ball of mass 1kg having kinetic energy 0.5J is (a) 6.626 × 10  34m (b) 13.20 × 10  34m (c) 10.38 × 10  21m (d) 6.626 × 10  34A ​

Answer 1

Answer:

B. ............. please follow me and mark it as brainliest

Answer 2

Answer:

λ= mvh

= 2mEh

= 2×1×0.5

6.6×10 −34

=6.6×10 −34m

Hence, the correct option is A
