An electron that has an instantaneous velocity of ???? = 2.0 × 106 m ???? ???? + 3.0 × 106 m ???? ???? is moving through the uniform magnetic field ???? = 0.030T ???? − 0.15T ???? . (a) Find the force on the electron due to the magnetic field (b) Repeat your calculation for a proton having the same velocity.

Answers

Answer 1

Answer:

Explanation:

It is given that,

Velocity of the electron, $v=(2* 10^6i+3* 10^6j)\ m/s$

Magnetic field, $B=(0.030i-0.15j)\ T$

Charge of electron, $q_e=-1.6* 10^(-19)\ C$

(a) Let $F_e$ is the force on the electron due to the magnetic field. The magnetic force acting on it is given by :

$F_e=q_e(v* B)$

$F_e=1.6* 10^(-19)* [(2* 10^6i+3* 10^6j)* (0.030i-0.15j)]$

$F_e=-1.6* 10^(-19)* (-390000)(k)$

$F_e=6.24* 10^(-14)k\ N$

(b) The charge of electron, $q_p=1.6* 10^(-19)\ C$

The force acting on the proton is same as force on electron but in opposite direction i.e (-k). Hence, this is the required solution.

One student did an experiment on the rock cycle. The steps of the experiment are shown below.

Collect five pieces of wax of different colors.
Use a plastic knife to scrape off thin shavings of the pieces of wax.
Pile the wax shavings of different colors one over the other.
Hold the pile of wax shavings in the palm and squeeze it for two to three minutes. Fold the pile and squeeze it in the palm again for a minute.
What does the student's experiment most likely demonstrate about the rock cycle?

a. Weathering can change igneous rocks into sediments.
b. Weathering can change metamorphic rocks into sediments.
c. Heat and pressure can change igneous rocks into metamorphic rocks.
d. Heat and pressure can change sedimentary rocks into metamorphic rocks.

Answers

First, when the student added the layers of wax over each other, this became a representation of sedimentary rocks.

Then the student folded his/her palm and squeezed the layers of wax. This means that the student applied heat and pressure on the wax (sedimentary rocks)

Referring to the diagram below which represents the rock cycle, we will find that applying heat and pressure on sedimentary rocks would convert these rocks into metamorphic rocks.

Based on the above, the best choice would be:
d. Heat and pressure can change sedimentary rocks into metamorphic rocks.
