Murljashka [212]

Answer:

Explanation:

In the whole process , electric potential energy is converted into kinetic energy .

Kinetic energy = 3.83 MeV

= 3.83 x 1.6 x 10⁻¹⁶ J

= 6.128 x 10⁻¹⁶ J .

Let the closest distance of approach be r .

Electric potential energy = k Q q / r , Q is charge on nucleus , q is charge on alpha particle , r is closest distance .

Electric potential energy = 9 x 10⁹ x 79 x 1.6 x 10⁻¹⁹ x 2 x 1.6 x 10⁻¹⁹ / r

= 3640.32 x 10⁻²⁹ / r

So,

6.128 x 10⁻¹⁶= 3640.32 x 10⁻²⁹ / r

r = 3640.32 x 10⁻²⁹ / 6.128 x 10⁻¹⁶

= 594.05 x 10⁻¹³

= 59.405 x 10⁻¹²

= 59.405 pm .

Tema [17]

Answer:

The absolute value of the angular deviation is 39.3°.

Explanation:

Given that,

Current = 1.1 A

Distance = 0.9 cm

Magnetic field = 20μT

We need to calculate the magnetic field due to wire

Using formula of magnetic field

$B=\dfrac{\mu_{0}I}{2\pi d}$

Put the value into the formula

$B=\dfrac{4\pi\times10^{-7}\times1.1}{2\pi\times0.9\times10^{-2}}$

$B=24.4\times10^{-6}\ T$

$B=24.4\ \mu T$

We need to calculate the absolute value of the angular deviation

Using formula of direction

$\theta=\tan^{-1}(\dfrac{B_{E}}{B_{w}})$

$\theta=\tan^{-1}(\dfrac{20 \mu}{24.4 \mu})$

$\theta=39.3^{\circ}$

Hence, The absolute value of the angular deviation is 39.3°.
