The electric field generated by a proton is a radial field, so we would see the field lines going radially from the proton toward every direction. I've attached a picture representing the electric field generated by a positive charge, such as a proton, and we can see the field lines going radially from the charge toward every direction.
Answer:
The maximum wavelength is 492 nm.
Explanation:
Given that,
Angular separation 
Suppose a telescope with a small circular aperture of diameter 2.0 cm.
We need to calculate the maximum wavelength
Using formula of angular separation


Put the value into the formula

For small angle 



Hence, The maximum wavelength is 492 nm.
If the probes are identical, then the one that feels a larger gravitational
force is orbiting closer to Jupiter than the other one is.
If they're not identical, then the one with greater mass will feel more
gravitational force than the one with less mass, even if they're both
the same distance from Jupiter. (We know this from the experimental
observation that fatter people weigh more, even on Earth.)
To solve this problem we will apply the definition of Newton's second law, which says that force is equivalent to body mass by acceleration. In this case the mass of the trailer is 325Kg and its acceleration is
, so we will proceed to replace and multiply these values to find the net force on this object.


F= 698.75N
Under the reference system in which the direction of travel is the positive direction, the direction of the force will be positive.
