A body of mass 2 kg thrown vertically upwards with a velocity 40 m/s comes to instantaneous rest at a height 50 m. Is there any other force (other than gravitational force), if yes then calculate the value. Ans) Yes , a force due to air drag will be there , to calculate this wehave to first find work done by air drag..Acc. To work-energy theoremWgravity + Wair drag = change in K.E.-Mgh +Wair drag = change in K.E.Wair drag =change in K.E. +mgh=[0-1/2mu2] +mgh = -1/2 x 2 x (40)2 + 2x 10 x 50 = -1600+1000 = -600Jnow w.d. = F x sF= -600/50 = -12N
A 25cm long conductor moves at a uniform speed of 8m/s by a uniform magnetic field of flux density 1.2T. Verify the current flowing in the conductor when (a) Its ends are o

HYSTERESIS LOOP: A ferromagnetic material retains some magnetism after the magnetising force is removed. The BH curve (O to Q) will therefore only be followed once, on initial
a) Two charges of the value 15X10 -9 coulomb and 30X10 -9 coulomb are locate at a distance 6 cm. Determine the intensity of electric field at point which is at a distance 2 cm fro
A cyclist rides at a constant speed of 12.0 m/s for 1.20 min and then coasts to a stop with uniform acceleration 21.2 s later. If the total distance travelled is 1321 m, then w
why deflection magnetometer can not be worked at poles?
It is the energy possessed by a body because of the interactive forces inside the object. This may be defined as the work done in assembling all the particles of a body in a exact
