Graph D; They have the same slope, but start at a different distance.
The force on a charged particle on a magnetic field is given by:

where B is the magnitude of the field, q is the charge of the particle, v is its velocity and θ is the angle between the field and the velocity of the particle.
In this case we have that:
• The magnitude of the field is 0.09 T.
,
• The charge of the particle is 3.2 x 10 –19C .
,
• The velocity is 3.0 × 10 4 m/s
,
• The angle between the field and the velocity is 90°, since they are perpendicular.
Plugging these we have:

Therefore, the force on the charge is:
Answer: -0.5 D
Explanation:
The resultant power can be defined as the sum of powers of all the lenses placed in contact together.
P =P₁ + P₂ + P₃ +....
It is given that power of the concave lens is, P₁ = -2 D
Power of the convex lens is, P₂ = +1.5 D
Thus, the resultant power when these two lenses are placed in contact with each other are: P = P₁ + P₂ = -2 D + 1.5 D = -0.5 D.
Answer: passes through Earth's shadow.
Explanation:
During a total lunar eclipse, the Earth lies between the Sun and the moon. All three are aligned in one straight line.
The moon does not have its own light. It reflects the sunlight. During total lunar eclipse, the earth comes between the sun and the moon and blocks the sunlight. Thus, the moon passes through the Earth's shadow and appears dark.
