Acharge of 8.4 × 10–4 c moves at an angle of 35° to a magnetic field that has a field strength of 6.7 × 10–3 t. if the magnetic force is 3.5 × 10–2 n, how fast is the charge moving?

The charge is moving with the  velocity of .

Explanation:

Given that,

Charge

Angle = 35°

Magnetic field strength

Magnetic force

We need to calculate the velocity.

The Lorentz force exerted by the magnetic field on a moving charge.

The magnetic force is defined as:

Where,

F =  Magnetic force

q = charge

B = Magnetic field strength

v = velocity

Put the value into the formula

Hence, The charge is moving with the  velocity of .

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
