Answer:
W from -ve x-axis
Explanation:
electrostatic force is given by
if both charge have different signs, Force will be attractive, and if both charge have same signs, force will be repulsive .
Now Net force will be
force between q1 and q3 is repulsive and towards -ve x-axis, which is
where q3 = 5.0nC {GIVEN}
force between q2 and q3 is attractive and towards +ve y-axis, which is
Now given that
q_1 = 6 nC, q_2 = -1 nC, q_3 = 5.0 nC
r_13 = 0.30 m
r_23 = 0.10 m
total force will be
F_3 =
magnitude of force can be calculated as
Direction W from -ve x-axis
Direction = 180 - 56.31 = 123.69 anti- Clockwise from +ve x-axis
Grass obtains 10% of the energy of the Sun. When a mouse eats the grass, it gets only 1% of the Sun's energy while 9% is lost as heat. It has already been known that only 10% of energy gets transferred from one link of the food chain to another. The answer to this question can be easily deduced from this fact.
