Two identical conducting spheres, A and B, sit atop insulating stands. When they are touched, 1.51 × 1013 electrons flow from sp

Explanation:

The formula for the electric field produced by an infinite sheet of charge is outlined below.

               E =

where,   is the surface charge density

Following this, the formula for the electric force acting on a proton is given as:

             F = eE

where,    e is the charge of a proton

According to Newton's second law of motion, the overall force on the proton can be expressed as follows.

                       F = ma

                 a =

                    =

                     =

According to kinematic equations, the proton's speed in the perpendicular direction can be described as follows.

                     =

                     =

                     = 683.974 m/s

Thus, the overall speed of the proton can be calculated as follows.

                v' =

                    =

                    = 1178.73 m/s

Consequently, we conclude that the proton's speed is 1178.73 m/s.

Answer:

Height (h) = 17 m

Velocity (v) = 18.6 m/s

Explanation: This problem can be solved using kinematic motion equations.

Given Data

Initial velocity (u) = 0

Acceleration (a) = g

Time (t) = 1.9 seconds

First, we calculate the height.

Then, we find the final velocity

The acceleration graph is a linear representation described by y=9.8, as it remains constant:

The velocity graph can be represented by y=9.8x (where y signifies velocity and x indicates time):

The displacement graph can be described as y=4.9x^2 (with x as time and y as displacement):

These graphs apply exclusively from x=0 to x=1.9, so disregard other sections of the graphs.
