The ground state energy of a particle in a one-dimensional infinite potential well of width 1.5 nm is 20 eV. The ground state energy of the same particle in a one-dimensional finite potential well with U_0 = 0 in the region 0 < x < 1.5 nm, and U_0 = 50 eV everywhere else, would be: A) equal to 20 eV.
B) greater than 20 eV.
C) less than 20 eV.
D) The particle would not have a ground state.

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

a electromagnetic waves

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
