When a nucleus of 235U undergoes fission, it breaks into two smaller, more tightly bound fragments. Calculate the binding energy per nucleon for 235U and for the fission product 137Cs .

An electron accelerated over a 21.4 kV potential, such as in a TV tube, has a wavelength of about 5.3 103.

When an electron is driven through a potential, V, its wavelength,, may be calculated using the formula = h/2mV, where h is Planck's constant. The wavelength of an electron accelerated via a 21.4 kV potential can be computed using the formula: = 6.626 x 10-34 Js / 2. (9.11 x 10-31 kg) (21.4 x 103 V)

λ = 1.19 x 10-10 m

The above expression can be used to determine the electron's wavelength because it is assumed that the electron behaves non-relativistically. The end result is a wavelength of 119 pm, or 1.19 x 10-10 m. (picometers). This wavelength is extremely tiny, measuring roughly 1/500th the size of a hydrogen atom.

A weight is attached to the other end of the pulley and released, resulting in 3-kg mass to rise 50 cm in 1.0 s.  The mass of the weight is 3.68 kg

The problem can be solved using the equation of motion:

s = u . t + 1/2 a . t²

Where:

s = distance

u = initial velocity

t = time period

a = acceleration

Substitute the given parameters:

s = 50 cm = 0.5 m

u = 0

t = 1

Hence,

1/2 a = 0.5

a = 1 m/s²

After obtaining the acceleration, a, use the Newton's 2nd law of motion.

Hence,

T - mg = ma

T = m (g + a)

Let M = mass of the weight.

m = 9.10939  × 10⁻³¹ kg

E = 0.18 kV/m = 180 V/m

B = 1.1 mT

where,

q is charge on electron

m is mass of electron

E is electric field

B is magnetic field

We know the kinetic energy of electron is calculated by

K.E = 1/2 (mv² )

∴ v = F / qB

∵ F = Eq

∴ F = 180 × 1.60218 × 10⁻¹⁹

∴ F = 288.3 × 10⁻¹⁹

∴ F = 2.8 × 10⁻¹⁷ N

Now,

v = F / qB

∴ v = (2.8 × 10⁻¹⁷ ) / (1.60218 × 10⁻¹⁹ ×1.1 )

∴ v = (2.8 × 10⁻¹⁷ ) / (1.7  × 10⁻¹⁹ )

∴ v = 1.64 × 10²

∴ v = 164 m.s

Now to calculate K.E,

K.E = 1/2 (mv² )

∴ K.E = 1/2 (9.10939  × 10⁻³¹ × 164²)

∴ K.E = 1/2  (9.10939  × 10⁻³¹ × 26896)

∴ K.E = 1/2 (245006.15   × 10⁻³¹ )

∴ K.E = 122503   × 10⁻³¹
