Uncertainity in position of a minute particle of mass 25 g in space is 10^(-5)m. What is the uncertainity in its velocity (in ms^(-1)) ? (h = 6.6 xx 10^(-34) Js)

Uncertainity in position of a minute particle of mass 25 g in space is

1.	Uncertainity in position of a minute particle of mass 25 g in space is 10^(-5)m. What is the uncertainity in its velocity (in ms^(-1)) ? (h = 6.6 xx 10^(-34) Js)
Answer» 23.5 26.9 66.37 73.1 Solution :`E = (HC)/(lambda) = 2.9 XX 10^(19)` J Total energy of 10 quanta `implies10 xx 2.9 xx 10^(-19) J` Energy stored for process `=(112 xx 4.18 xx 10^3)/(6xx10^(23)) = 7.80xx 10^(-19) J` % efficiency `=(7.80xx 10^(-19))/(29 xx 10^(-19)) xx 100 implies26.9 %`
