When horizontal force is applied on block then as per Newton's II law we will have
so here mass will be
now on same block F = 5 N is applied on surface of Moon
so on surface on moon we will have
so above is acceleration on surface of moon
In mechanics, the normal force<span> is the component, perpendicular to the surface (surface being a plane) of contact, of the contact </span>force<span> exerted on an object . We calculate as follows:
</span>∑F along x = 0 = F - Fn
<span>
Fn = F = mg = 7.52(9.81) = 73.77 N <------OPTION B</span>
Answer:
The temperature raise is = 0.14 [C]
Explanation:
In order to find the temperature difference we must use the following equation:
But first we need to find the original volume V:
When the volume is increased the diameter will be larger:
D1 = 0.125[m] + 0.0002[m] = 0.1252[m]
Therefore the new radius will be:
r1=0.0626[m]
The new volume is:
Replacing all the calculated values in the equation:
Answer:
Explanation:
mass of each ball, m = 1 kg
Let the charge on each ball is q.
If the balls remains fix then the gravitational force is balanced by the electrostatic force between them and as the gravitational force is attractive in nature then the electrostatic force should be repulsive in nature.
The charges should be of same sign to get the electrostatic force is repulsive in nature.
Let the distance between the two balls is d.
The electrostatic force between them is given by
... (1)
The gravitational force between the two balls is given by
... (2)
according to the question, gravitational force is equal to the electrostatic force, so by equation (1) and (2) ,we get
Thus, the charge on each ball is
