a. they are directly proportional to mass.
b. they are inversely proportional to the square of the distance.
c. they are inversely proportional to charge.
d. they are directly proportional to the square of the distance.

What will happen in a hybrid vehicle if current flow becomes too high due to a short?

The resistance of 100 w bulb is less than resistance of 40 w bulb. explain the reason.

Apoint charge +q is at the origin. a spherical gaussian surface centered at the origin encloses +q. so does a cubical surface centered at the origin and with edges parallel to the axes. select "true" or "false" for each statement below. the electric flux through the spherical surface is greater than that through the cubical surface. suppose (for this statement only), that q is moved from the origin but is still within both the surfaces. the flux through both surfaces remains unchanged. the area vector and the e-field vector point in the same direction for all points on the spherical surface. the e-field at all points on the spherical surface is equal due to spherical symmetry. the flux through the spherical gaussian surface is independent of its radius.
