Astick of length 6.2 cm has charged globes on either end, one charged to 16 μc, while the other one is charged to 1μc. the rod is placed perpendicular to a 1174 n/c field. what is the force on the stick?
what is the polarization of the bar?
how much torque does it feel?

Net force = 0.0191 N

T=0.00054 N.m

p=99.2 μC.cm

Explanation:

Given that

L= 6.2 cm

q₁= 16μC

q₂=1μC

E= 1174 N/C

We know that

F = q E

F₁ = q₁ E

F₁ = 0.018 N

F₂=q₂ E

F₂=0.0011 N

Net force = F₁+F₂

Net force = 0.0191 N

Torque ,T

T = (F₁-F₂) L/2

T = (0.018 - 0.0011 ) x 0.032

T=0.00054 N.m

Polarization ,p

p= q d

p= 16 x 6.2 μC.cm

p=99.2 μC.cm

1= 26.17

2= 1.17

3=30.86

4=5.86

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
