We know that,
Given that,
V = 3000 V
K = 7.06 × 10-6 Nm/rad
Given that,

N/m. This means that the force required to deflect the voltmeter's needle by a certain amount is directly proportional to that amount. For example, if it takes a force of 0.1 N to deflect the needle by 1 mm, it would take a force of 0.2 N to deflect it by 2 mm, and so on.
To calculate the force required to deflect the needle of the voltmeter by a certain amount, we can use the formula:
F = kx
where F is the force, k is the spring constant, and x is the displacement (or deflection) of the needle.
For example, if the needle is deflected by 2 mm, the force required would be:
F = 7.06 N/m x 0.002 m = 0.01412 N
Similarly, if the needle is deflected by 5 mm, the force required would be:
F = 7.06 N/m x 0.005 m = 0.0353 N
To calculate the force required to deflect the needle of the voltmeter by a certain amount, we can use the formula:
F = kx
where F is the force, k is the spring constant, and x is the displacement (or deflection) of the needle.
For example, if the needle is deflected by 2 mm, the force required would be:
F = 7.06 N/m x 0.002 m = 0.01412 N
Similarly, if the needle is deflected by 5 mm, the force required would be:
F = 7.06 N/m x 0.005 m = 0.0353 N
