# Physic for A level & UTME

Simplifying physics for better understanding for students to excel in ‘A level’ and UTME

## Notes on Surface Tension

The surface of the liquid behave lika a membrane under tension, surface tension arises because the molecules of the liquid exert attractive forces on each other. There is zero net force in a molecule inside the volume of the liquid, but a surface molecule is drawn into the volume. Thus, …

## Notes on magnetic field for Cambridge A level and UTME

Magnetic field is a region of space where a magnet or a current carrying conductor or a moving charge experience a magnetic force. Magnetic field is directed from a North pole to a South pole. A uniform field, within which the field strength is the same at all points, could be …

## Notes on ideal gases for Cambridge A level and UTME

An ideal gas is one that obeys the gas laws, and equation of state for ideal gas, at all temperature, pressure and volume. This means Ideal gas obeys pV = nRT P = Pressure V = Volume T = Temperature R = universal gas constant n= number of moles Infer …

## How to solve questions on capacitance of capacitor for Cambridge A level and UTME

Question 1 Three capacitors, each of capacitance 48 μF, are connected as shown in Fig below (a) Calculate the total capacitance between points A and B. (b) The maximum safe potential difference that can be applied across any one capacitor is 6 V. Determine the maximum safe potential difference that …

## Notes on capacitance of a capacitor for Cambridge A level and UTME

Capacitance of a capacitor is the charge stored on one plate per unit of potential difference between the plates c is the capacitance Q is the charge v is the potential difference Farad is the unit of capacitance Uses of capacitor it stores energy smoothing circuit separate charges blocking D.C …

## Notes on gravitational field for Cambridge A level and UTME

According to Newton, all masses create a gravitational field in the space round them. The field give rise to a force on any object having mass placed in this field. The moon orbits the earth because it experiences a gravitational force due to the earth’s gravitational field. If an object …
