Answer:
8.75×10⁻⁴ N. due east
Explanation:
Electric Field: This is defined as the force per unit charge which it exerts at that point. Its direction is the force exerted on a positive charge. The S.I unit of electric field is N/C.
The expression for electric field is given as,
E = F/q
where E = Electric field, F = Force, q = charge.
Making F the subject of the equation,
F = E×q.................... Equation 1
Given: E = 250 N/C, q = 3.5 µC = 3.5×10⁻⁶ C.
Substitute into equation 1
F = 250×3.5×10⁻⁶
F = 875×10⁻⁶
F = 8.75×10⁻⁴ N. due east
Hence the force is 8.75×10⁻⁴ N. due east
The net force on the object as described is; 58.84N
Two forces acting on the object are;
- The <em>applied force and the frictional force.</em>
In essence; the frictional force can be evaluated as;
- Frictional force; = coefficient × Weight of object.
- Frictional force = 0.21 × 20 × 9.8.
- Frictional force = 41.16N
- The Net force = Applied force - frictional force
Net Force = 58.84 N.

Explanation :
is silver nitrate. In this compound, one atom of silver, one atom of nitrogen and three atoms of oxygen are present.
We know from the concept of mole concept that the number of molecules, atoms or ions present in a substance is known as one mole.
The number of particles in one mole of a substance is defined as Avogadro's number.
So, we can say that silver, nitrogen and oxygen are present in .
