The volume charge density of a solid sphere of radius 0.75 m is 0.25 nCm^(-3). Apply Gauss's law to calculate the (a) electric flux through the sphere and (b) electric field at a distance of 1.5m and at a distance of 0.50m from the centre of the sphere,respectively.If this sphere were made of conducting material,what would the values of the electric fields be at these distances?

3.To determine the area of cross-section of a given wire by measuring its radius?
4.To determine the thickness of glass plate and diameter of a wire?
5.To determine the value of acceleration due to gravity and to draw I-T2graph?
6.To experimentally verify Boyle's law using Quill tube method?
7.To determine the velocity of sound in air at room temperature and to calculate its value at O°Cusing two tuning forks.

to measure the length of a cylinder and calculate its volume?

If V(a)=300volt, and V(a->b)=50volt. a test charge (s) was placed 6cm away from A, find the following:
1)the amount and type charge S?
2) the distance between A and B?

B--------A--------S
? 6cm

Consider rectangle PQRS of sides 20cm and 15cm with charges 2microC, 4microC, 9microC at P, Q and S respectively. Determine the resultant electric field intensity at the fourth corner, R of the rectangle due to the charges P, Q and S.
Hence determine the resultant force that would act on a fourth charge 6microC placed at point R due to the other charges at P, Q and S.

If the observer was located in the X-Y plane the magnitude of R would vary as the particle gyrates, and therefore a phase lag term would appear. Calculate the radiation field for a point in the X-Y plane (use a point such as x = kr0 with k > 1), and again show what happens when k>>1.

An electron with a speed of 5.00 × 10^8 cm/s enters an electric field of magnitude 1.00 × 10^3 N/C, traveling along a field line in the direction that retards its motion. (a) How far will the electron travel in the field before stopping momentarily, and (b) how much time will have elapsed? (c) If the region containing the electric field is 8.00 mm long (too short for the electron to stop within it), what fraction of the electron’s initial kinetic energy will be lost in that region

When an object moves through a Vacuum of Space (without applying any External Force is on it). It Continue moving. But Higgs Field Suggest it resist the object to Change Motion State (Rest or Moving) & i.e it's mass. Higgs are everywhere it will make the object stop in Vacuum of Space?
