Answer» Correct Answer - A::C::D `Delta = [(1)/(100) xx (1)/(10)c] = ( 3 xx 10^(8) m s^(-1))/(1000) = 3 xx 10^(5) m s^(-1)` `:. Delta p Delta x ge (h)/(4pi)` `Delta x ge (1)/(Delta p)xx(h)/(4pi)` `ge (1)/(m Delta v) ,(h)/(4pi)` `ge (1)/(9.1 xx 10^(-31)(kg)) xx (1)/( 3 xx 10^(5)m s^(-1)) xx (6.626 xx 10^(-34)(Js))/(4 xx 3.14)` `ge 1.93 xx 10^(-10)m` |
