Acharge of −3.77 µc is located at the origin, and a charge of −4.92 µc is located along the y axis at 2.86176 m. at what point along the y-axis is the electric field zero? the value of the coulomb constant is 8.99 × 109 n · m2 /c 2 .

1.336 m

Explanation:

q = - 3.77 micro C at y = 0 m

Q = - 4.92 micro C at y = 2.86176 m

Let the electric field is zero at P which is at a distance y from origin.

Electric field at P due to q is equal to the electric field at P due to Q.

2.86176 - y = 1.142 y

2.142 y = 2.86176

y = 1.336 m

Thus, the electric field is zero at y = 1.336 m.

the answer is b, have negligible mass

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
