Answer:
Distance is 5.0 km and displacement is 0 km.
Explanation:
The diagram is shown below.
Distance is the total length that the truck covers along the complete journey. The truck moves from a stone quarry covering a length of 2.5 km and then again come back to the same point and thus covering another 2.5 km. Therefore, the total length covered by the truck is the sum of forward and backward paths which is equal to 5.0 km.
Now, displacement depends only on the initial and final position. It is given as the difference of final position and initial position. So, the truck starts from stone quarry and returns back to the same position. So, the initial position and final position is same. Therefore, the difference is 0 and hence displacement is zero.
Electric field is defined as force per unit charge.
So it is given by
now we can find electric field by
So field strength is 0.75 N/C.
