Answer:
Concave mirror,-20.48m
Explanation:
Concave mirrors-This is because the objects are made smaller by the mirror, so they appear farther away.
#we find the image distance from the magnification:
#We find the focal length from:
r=2f=-10.24m*2=-20.48m
#The mirror has a negative radius(-20.48m) of curvature since its vertex lies to the right of the center of curvature
Explanation:
Below are attachments containing the solution.
Answer with Explanation:
We are given that
x=-2.6 cm to x=2.6 cm
Linear charge density=
Length of wire=
Length of wire=
1 m=100 cm
We know that
a.Linear charge density=
Where Total charge =Q
Length=L
Total charge,Q=
Using the formula
Total charge,Q=
b.y=4 cm=
1 m=100 cm
Electric field on the y-axis is given by
Using the formula
c.y=12 cm=
Using the formula
Answer:
bar one:constant acceleration
bar two:remains stationary
bar three:constant acceleration
