4.266 m is the radius of the circular path the electron follows.
Given
Speed of electron (v) = 7.5 × 10⁶ m/s
Earth's Magnetic Field (B) = 1 × 10⁻⁵ T
We already know that
Mass of electron (m) = 9.1 × 10⁻³¹ kg
Charge on electron (q) = 1.6 × 10⁻¹⁹ C
According to the formula
Radius of circular path(r) = mass on electron × speed/ Charge × Magnetic field
Radius of circular path(r) = m × v/q × B
Put the values into the formula
r = 9.1 × 10⁻³¹ × 7.5 × 10⁶/ 1.6 × 10⁻¹⁹ × 10⁻⁵
On solving, we get
r = 4.266 m
Hence, 4.266 m is the radius of the circular path the electron follows.

Answer:
Se necesita la información de las siguientes variables:
(i) Fuerza normal entre los pies y la superficie.
(ii) Masa del atleta de halterofilia.
(iii) Masa de la barra de pesas.
(iv) Aceleración gravitacional.
(v) Fuerza normal entre la barra de pesas y la superficie.
(vi) Aceleración neta del centro de gravedad del sistema.
Explanation:
Sea el conjunto del atleta de halterofilia y la barra de pesas el sistema físico a estudiar. El fenómeno de levantamiento puede modelarse como traslación pura. Por las leyes de Newton tenemos que se necesita las siguientes variables para determinar la magnitud de la fuerza para levantarla (fuerza normal entre la mano y la barra de pesas) se requiere las siguientes variables:
(i) Fuerza normal entre los pies y la superficie.
(ii) Masa del atleta de halterofilia.
(iii) Masa de la barra de pesas.
(iv) Aceleración gravitacional.
(v) Fuerza normal entre la barra de pesas y la superficie.
(vi) Aceleración neta del centro de gravedad del sistema.
1. it`s due to the gravitational pull of earth which causes Moon to orbit the Earth.
2. No,it`s not always noticeable.You must have heard that earth pulls apple so it falls downward but the fact is apple also pulls earth but the pull isn`t noticeable.
3. I have only one thing that is the distance between the masses.
4. The quantity of matter contained in a body is called it`s mass whereas weight of an object is the force of attraction with which it is attracted towards the centre of a planet.Mass of an object is constant everywhere bt weight of an object varies from place to place.Mass is measured by beam balance whereas Weight is measured by spring balance.
5. You will fall back on the surface of earth.It happens because of the force of gravity of the earth.
6. If u jump on the moon u will float away(I guess).
7. Weightlessness is a condition where weight of an object is experienced to be zero.The mass doesn`t change as it remains constant everywhere.I will add an image for this one which may help you.
Answer:
The answer is the First One
Explanation:
Electromagnets can work with a magnetic source, and not just electric. sorry if my answer turns out to be wrong
