Can we increase/decrease the range of a given ammeter?

Can we increase/decrease the range of a given voltmeter?

For a given impact parameterb,does the angle of deflection increase or decrease with the increase in energy?

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : The range of an ammeter can be both increased or decreased. Reason : The required shunt resistance can be calculated by using the relation, R= (GS)/(G +S)

for a given energy of the projectile,does the scattering angle increase or decrease wtih the increase in impact parameter?

Choose the correct alternative :- Acceleration due to gravity increases//decreases with increasing altitude.

An ammeter reads upto 1 ampere. Its internal resistance is 0.81 ohm. To increase the range to 10 A the value of the required shunt is
