de broglie wavelength has a formula
where h is planck' s constant and
m is mass of e-(9.1 ×10–³¹ kg)
v is velocity which is given
10 times the velocity of light that is
10 times the velocity of light that is 3×10^8×10 that is 3× 10^9 m /sec
hence having the value of
planck's constant as 6.63× 10–³⁴ js
wavelength = 6.63× 10–³⁴/ (9.1 ×10–³¹×3× 10^9)
wavelength = 6.63 × 10–¹² /3× 9.1
0.242 × 10–¹² m Or 2.42× 10-¹³ m
this is ur ans
hope it helped mark me brainliest
