Answer:
Explanation:
Given
Average Electric Field Strength
Considering charge distribution to be uniform and earth to be symmetrical
Using Gauss law
Also
here Electric Field is acting inward therefore
Answer:695.5 N
Explanation:
mass of child
Length of chain
Tension in each chain
(a)Tension at bottom point
At lowest Point
(b)Force exerted by Seat will be Equal to Normal reaction
<span>(a)
Taking the angle of the pitch, 37.5°, and the particle's initial velocity, 18.0 ms^-1, we get:
18.0*cos37.5 = v_x = 14.28 ms^-1, the projectile's horizontal component.
(b)
To much the same end do we derive the vertical component:
18.0*sin37.5 = v_y = 10.96 ms^-1
Which we then divide by acceleration, a_y, to derive the time till maximal displacement,
10.96/9.8 = 1.12 s
Finally, doubling this value should yield the particle's total time with r_y > 0
<span>2.24 s
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
