An accelerated charge particle radiates. So, in the light of principle of equivalence, does a charge particle also radiate when it is in a gravitational field? Sorry if the question doesn't make any sense.

When a charge moves through a gravitational field, it experiences a force due to the gravitational interaction between the charge and the mass that is creating the field. This force can either accelerate or decelerate the charge depending on the direction of its motion relative to the gravitational field.
The electric force and gravitational force on a moving charge are independent of each other. The electric force depends on the charge and its position relative to other charges, while the gravitational force depends on the mass and the distance between objects. Both forces can act simultaneously on a moving charge, causing it to follow a curved path.
The stronger the gravitational field, the greater the force on the moving charge, which can lead to a more significant change in its motion. In a stronger gravitational field, the charge will accelerate or decelerate more quickly, causing it to move at a faster or slower speed, respectively.
Yes, a moving charge can escape from a gravitational field if its speed is greater than the escape velocity, which is dependent on the mass and shape of the gravitational field. If the charge's speed is less than the escape velocity, it will be pulled back towards the source of the field.
In a gravitational field, the force on a moving charge will always be directed towards the source of the field, while in a uniform electric field, the force on a moving charge will always be parallel to the electric field lines. Additionally, in a gravitational field, the force on the charge is dependent on its mass, while in an electric field, it is dependent on its charge.
