Calculate the wavelength associated with cricket ball ofmass of 150 g travelling with a velocity of`25ms^(-1)`

Explanation

According the de -Broglie equation
` lamda =- (h ) /(mv ) `
` h=` Planck.s constant
` = 6.626 xx 10 ^(-34)` Js
`=m=150 g`
`=(150 )/(1000)kg `
V `= 25 ms^(-1)`
putting in equation We get
` lamda = ( 6.626 xx 10 ^(-34)Js )/( ((150 )/(1000)kg) xx 25 ms^(-1))`
` lamda = 1.766xx10^(-34)m (j= Kg m^2 s^(-2))`
