An alpha particle (q = +2e, m = 4.00 u) travels in a circular path of radius 5.99 cm in a uniform magnetic field with b = 1.43 t. calculate (a) its speed, (b) its period of revolution, (c) its kinetic energy, and (d) the potential difference through which it would have to be accelerated to achieve this energy.

a)

b)

c)

d) 175000 volts

Explanation:

a)

 = magnitude of charge on the alpha particle = 2 x 1.6 x 10⁻¹⁹ C = 3.2 x 10⁻¹⁹ C

 = mass of alpha particle = 4 x 1.67 x 10⁻²⁷ kg = 6.68 x 10⁻²⁷ kg

 = radius of circular path = 5.99 cm = 0.0599 m

 = magnitude of magnetic field = 1.43 T

= speed of the particle

Radius of circular path is given as

b)

Time period is given as

c)

Kinetic energy is given as

d)

ΔV = potential difference

Using conservation of energy

q ΔV = K

(3.2 x 10⁻¹⁹) ΔV = 5.6 x 10⁻¹⁴

ΔV = 175000 volts

because growing process had stoped after 4-5 year

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
