Answer:

The power of the bulb is reduced to a quarter

Explanation:

The power in an electrical circuit is

P = V I = I² R

If the dimmer cuts the current in half

I = I₀ / 2

The resistance of the light bulb after hot is little affected by small changes in the current

We substitute in the equation

P = I₂ R

P = (I₀ /2)² R

P = ¼ I₀² R

P = ¼ P₀

The power of the bulb is reduced to a quarter

Sergeeva-Olga [200]

Answer:

$B = 1.03 \times 10^{-4} T$

Explanation:

As we know that magnetic force on a moving charge is given by the formula

$F = q(\vec v \times \vec B)$

so we will have

$F = qvBsin\theta$

now we will have

$F = 4.6 \times 10^{-3} N$

$q = 8.1 \mu C$

$\theta = 50^o$

$v = 7.2 \times 10^6 m/s$

now we have

$4.6 \times 10^{-3} = (8.1 \times 10^{-6})(7.2 \times 10^6)Bsin50$

$B = 1.03 \times 10^{-4} T$
