Answer:4s^-1
Explanation:Tangential Acceleration=v^2/r=(20)²/100=400/100
The term Point Charge describes a model in which a charge takes up no space and acts uniformly on its surroundings. A Point Charge also creates lines that are uniform in nature and can go both outwards or inwards. When it goes outwards, it shows a positive charge and when it goes inwards then it shows a negative charge.
Explanation:
i am sorry but i so nota know
To give solution to the exercise we must use the concepts of Torque, Vector magnitude and vector direction of the forces.
For the given problem we have to


In this way the torque acting on the particle as a function of distance and time is,

The net torque acting on the particle is



PART B) The direction of the torque is given by,




Therefore the torque direction is 48.04° below the x axis.
