Answer:
d) F
Explanation:
According to columb's law:
"The magnitude of electrostatic force between two charges is directly proportional to the product of magnitude of two charges and inversly proportional to separation between them."
If q₁ and q₂ are magnitude of two charges, d is distance between them and k is dielectric constant, then force F is given by
According to this force exerted on point charge Q is same as that of 3Q, so force point 3Q charge experience is also F
Since the motor cycle was moving at 36 m/s before the brakes were applied, the initial velocity
The motorcycle traveled 23m before stopping, that means
Since the motorcycle stopped moving the final velocity is zero.
We can use this 'suvat' equation of linear motion.
Plugging in the above values gives,
We can use the equation
to find the time the motorcycle took to stop.
