What is the force exerted on a charge of 2. 5 µC moving perpendicular through a magnetic field of 3. 0 × 102 T with a velocity o

emmasim [6.3K]

As per the problem, the charge is of 2.5μC, moving in magnetic field $3\times10^{2}$ T and having velocity $5\times 10^{3}$ m/s, the force comes out to be 3.75N

<h3>what is magnetic force?</h3>

Magnetic force is the force experienced by the object inside the magnetic field or flowing current across the conductor. This force is caused due to the movement of charges.

The force exerted is magnetic force which is given as,

$F= QVBsin\theta$

here,

Q= charge

v= velocity

B= Magnetic field and

$\theta$ =Angle of object from magnetic field

$F=2.5\times10^{-6} \times 5\times10^{3} \times3\times10^{2}\times sin90$

$F=3.75N$

Answer:

(a) The initial speed required is 13116 m/s

(b) The escape speed is 10394 m/s

This problem involves the application of newtons laws of gravitation. The forces in action here are conservative and as a result mechanical energy is conserved.

The full calculation can be found in the attachment below.

Explanation:

In both parts (a) and (b) the energy conservation equation were used. Assumption was made that when the object is very far from the planet the distance from the planet's center approaches infinity and the gravitational potential energy approaches zero.

The calculation can be found below.
