Which figure represents the electric field lines of two negative point charges? Help

Answer:
The question is incomplete because the options are not given. We'll solve this question with the options.
There are two properties of negative charges which we have to consider to find the figure of its electrical field.
Firstly, for a negative charge, the electrical field lines are always directed radially outwards and they don't intersect.
Secondly, we know that similar charges repel each other, so there will be no electrical field present directly between these two negative charges. Electrical field line will be present between two charges only when there is a force of attraction.
Taking both of these facts into consideration, the electrical field line between two negatives is represented by the figure below.

Answer:
Velocity.
Explanation:
Projectile motion is characterized as the motion that an object undergoes when it is thrown into the air and it is only exposed to acceleration due to gravity.
As per the question, 'any change in the initial velocity of the projectile(object having gravity as the only force) would lead to a change in the range as well as the maximum height of the projectile.' To illustrate numerically:
Horizontal range: As per expression:
R= (*sin2θ)/g
the range depending on the square of the initial velocity.
Maximum height: As per expression:
H= ( *
θ
)/2g
the maximum distance also depends upon square of the initial velocity.
