The velocity associated with a proton in potential difference of 1000 V is `4.37 xx 10 ^(5) ms ^(-1).` If the hockey ball ofmass 0.1 kg is moving with this velocity, calculatethe walvelength associated with this velocity.

Explanation

We are given that
Mass of hackey ball `= 0.1 ` kg
Velocity `= 4. 37 xx 10 ^(5) ms ^(-1)`
We are to find out the wavelength assciated with velocity .
We know that
According to de-Broglie equation
`lamda = ( 6.626 xx 10 ^(-34) kg m ^(2) s ^(-1))/( 4. 37 xx 10 ^(5) s ^(-1) xx 0. 1 kg ms ^(-1))`
`lamda = 1. 51 xx 10 ^(-38) m.`
So, wavelength associated with hockey ball is `1. 51 xx 10 ^(-38)m.`
