Principles of Physics 2 Problem (Calculus based) Help A thin cylindrical shell of radius R and length L, like a soda straw, is uniformly charged with surface charge density η. What is the electric field strength at the center of one end of the cylinder? The answer is supposed to be , where E(sub 0) is epsilon 0 and the "n" is the surface charge density (η). Can someone explain how to get the answer? Kind of confused on what to do.

0 and 2 with an interval of 1 third between each pair of numbers

Explanation:

b

explanation:

bc its just b

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
