N a lab, two pieces of cellophane tape are placed on a lab table. They are quickly ripped off the lab table. Which would you predict would happen if the two pieces of tape were brought near each other?
A) The two pieces of tape would repel each other.
B) The two pieces of tape would attract each other.
C) There would be no attraction or repulsion between the pieces of tape.
D) There is no predictable result as the two pieces of tape are brought near each other.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

gets less

overcharge is the right answer system

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
