Particles q1, q2, and q3 are in a straight line. Particles q1 = -5.00 x 10-6 C, q2 = +2.50 x 10-6 C, and q3 = -2.50 x 10-6 C. Particles q1 and q2 are separated by 0.500 m. Particles q2 and q3 are separated by 0.250 m. What is the net force on q2?

a and c

c is 100% but i am confused in a

if they have a finite resultant

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.
