Calculate the work done by a 47 n force pushing a 0.025 kg pencil 0.25m against a force of 23 n

Find the electric field midway between a 2 -μC point charge which are 2.5 m apart.

What is the electric field at a distance of 10 cm from an isolated point charge of

With solution please?

1. Two point charges q1 = 5.25 x 10-9 C and q2 = -8.75 x 10-9 C are 1.00 m apart in air. (a) What

force exist between them? Is this an attractive or a repulsive force? (b) The charges are allowed

to touch and separate again by 1.00 m. What force exists between them now? Is this an

attractive or a repulsive force?

In an ac circuit it is containing resistance of 15 ohm and inductance of 0.3H in series with 50 Hz ac supply voltage.If the voltage across resistance and inductance is 10 volt and 15 volt respectively.Then determine the total input voltage of the circuit

 Look at the data: as the net force increased, what happened to the acceleration? Did it increase, decrease or stay constant? Why?
