How is same charge possible on both C3 and C4 and potential difference between B and A is different and P and A is different? and how is VAB = 2v using this ?

Homework Statement In the above circuit, find the potential difference across AB. 2. Solution Online "C34 = 4μf C2,34 = 12μf CEQ = 4.8μf q = CEQ x V the q on 1 is 48μC, thus V1 = q/c V1 = 6v VPQ = 10 - 6 = 4v By Symmetry of 3 and 4 , VAB = 2v" 3.My question...

Homework Statement Mass of Block A = 1 kg Mass of Wedge B = 2 kg Inclination of Wedge is 37° and Cos 37° = 4/5 The wedge is given an acceleration of 5 ms-2 Find - 1. Acceleration of Block wrt Wedge 2. Normal Force Homework Equations Newton's Law for a System (hereby referred as...

1.Decreases by X 2.cant figure out

So for const direction of pull, is The answer is VP(2+cosβ) ? If not, Plz tell me how to solve PLZ

Modified The quesion. I hope it will help u to understand my question. I want to give u 100 thanks at once but forum rules restricts me to only one

Plz explain what do you want to say? Is answer 2VP correct?

Homework Statement Find V if the pulley is massless, friction less and Can take any no of variables but V is be in terms of VP.Ignore gravity and other forces 2. The attempt at a solution If Pulley comes down by X, the length of string towards left(the side not fixed) will increase by...

When I had a school tour to A water park, there I observed that when a heavy boy used to slide down a water slide(and stop at β), he used to go further than where the ligher boy used to stop after sliding(α). But the friction will act more on Heavier then why is he going further?

Homework Statement In the arrangement shown, all surfaces are frictionless, mass of block M = 30 kg and m = 20 kg. If F = 180 N , Find accelerations of both the blocks 2. Doubt How much force will be applied on the larger block M by the pulley(coz of tension)? 1. T towards right 2. T towards...

Homework Statement Two blocks of mass m1 and m2 (m2 = 2 kg ; m1 = 3 kg)are connected with a spring moving on smooth plane. The acceleration of block of mass m2 is 2 ms-2, find acceleration of block with mass of 3kg. 2. The attempt at a solution Let external force of F be applied on Block...

Homework Statement In the arrangement shown, all surfaces are frictionless, mass of block M = 30 kg and m = 20 kg. If F = 180 N , Find accelerations of both the blocks 2. Doubt What amt of force will act on larger block M, just T(coz of horizontal string around the pulley) or...

Homework Statement A motorboat is observed to travel 10 km/hr relative to Earth in the direction 37° north of east. If the velocity of the boat due to wind ONLY is 2 km/hr westward and that due to current is 4 km/hr southward, what is the magnitude and velocity of the motorboat due to its own...
