Two point charges are placed as follows: charge q1 = -1.50 nC is at y = +6.00 m and charge
q2 = +3.20 nC is at the origin. What is the total force (magnitude and direction) exerted by
these two charges on a negative point charge q3 = -5.00 nC located at (2.00 m, -4.00 m)?
A capacitor consists of two square metal plates, each measuring 5.00 𝑥 10^−2m on a
side. In between the plates is a sheet of mica measuring 1. 00 𝑥 10^−4m thick.
(a) What is the capacitance of this capacitor? If the charge in one plate is
2. 00 𝑥 10^−8C.
(b) What is the potential difference and
(c) What is the electric field between the plates?
Given: Permittivity of Mica
(𝜖 = 4.8 𝑥 10^−11𝐶^2 / 𝑁. 𝑚^2)
A point charge of -6. 00𝑥10^−9C is 3.00m from point A and 5.00m from point B.
(a) Find the potential at point A and point B.
(b) How much work is done by the electric field in moving a 2.00 nC particle
from point A to point B?
A model car is moving around a circular track of radius 3.0 m at a speed of 1.5 m s−1 as shown in the figure. It takes the car 12.6 s to complete one full lap.
What is the magnitude of the average velocity of the car (a) between point A and point B? (in m s−1 to 2 s.f)
NOTE: The motion of the car is NOT an example of constant acceleration.
A point particle is projected from the top of a hill 5m above sea level. It is projected with initial horizontal speed of 2m/s.
a. How far from the foot of the hill does it land?
b. How long does it take to hit the ground?
c. With what speed does it hit the ground?
d. With what velocity does it hit the ground?
The driver of a car travelling at 2m/s hits the brakes which provides a steady deceleration of 3m/s2 , how far does the vehicle travel before coming to rest?
A stone is thrown into a well 6m deep. The stone is thrown from rest. How
long will it take before you hear the stone hit the floor of the well. Assume
speed of sound is 2m/s (this is not the actual speed of sound, please!!)?
A car is preceding down a 1 in 10 incline at 65KPH when it's brake are abruptly applied. How far does it skid along the road before stopping if the wheels lock and the coefficient of friction between the tyres and the road is 0.7 ?
A stone is thrown into the air with initial speed of 3m/s from the ground.
What time does it hit the ground? (Neglect air resistance)
what is the calculation and errors of simple pendulum expriment ?
