Answer:
The magnitude and direction of the magnetic field is 93.63 T in negative x direction.
Explanation:
Given;
speed of the electron in positive y direction, v = 2.0 x 10⁵ m/s
magnetic force on the electron, F in negative z direction = 3.0 x 10⁻¹² N
The magnitude of the magnetic force is given by;
F = Qv x B
B = F / Qv
The direction of the magnetic field is is as;
Based on the direction of magnetic force (negative z direction), the charge will be directed into negative y-direction because electron is negatively charged. Thus, the direction of the magnetic field will be in the negative x-direction
Therefore, the magnitude and direction of the magnetic field is 93.63 T in negative x direction.
Answer:
1. Emma standing on top of mountain
Since she is at the rest position and at some height from the ground so here energy is due to gravitational potential energy
So we have
gravitational potential energy
2. Emma jumping down from mountain top
Due to free fall Emma will start moving with some speed in downwards direction so here we have
motion energy
3. tension in rope at Emma’s lowest position
Due to stretch in the rope here position come to the lowest end and speed comes to zero so whole energy is converted into elastic potential energy
elastic potential energy
4. Emma bouncing back
Due to bouncing back she will again have its kinetic energy with some speed upwards
motion energy
It is the energy an object has because of its motion.
Answer:
60°
Explanation:
It will be equilateral triangle, you can prove with the cosine theorem.
1)P^2=P^2+P^2 - 2×P×P× cos A
2) cos A= P^2 / 2× P^2 = 1/2
cos A = 1/2
A = 60°
If you wrote this question right,it will be solved like this :)
