Answer:
a) 9.0
Explanation:
The force between two point charges, obeys Coulomb's Law, which can be written as follows:

As it can be seen, if the separation between the charges remains the same, the new value of the force will be directly proportional to the product of the charges.
If both charges are tripled, the mutual force between them will be changed in a factor equal to 3.0*3.0 = 9.0
Answer:
The electric force acting on the raindrop is 100 N.
Explanation:
Given;
charge of the raindrop, Q = 10 mC = 0.01 C
electric field strength, E = 10,000 V/m = 10,000 N/C
The force acting on the raindrop is given as;
Electric Force = electric field strength x charge of the raindrop
F = EQ
F = (10,000 N/C) (0.01 C)
F = 100 N
Therefore, the electric force acting on the raindrop is 100 N.
If E = 1/2 * m * v^2
v = (2E/m)^1/2
so the larger the mass, the higher the velocity hence taylor is moving faster

Answer:
Explanation:
The force that one atom exerts on the other is the negative derivative of the potential energy = 
F(x) = -
( -C₆ / x⁷) = - (- (-6) C₆ x⁻⁶ ⁻¹) = - 6C₆ /x⁷
when xis negative, F is positive and when x is positive, F is negative. It is therefore and attractive force and F is always directed to the center
